About daily.surf
daily.surf is ten free daily games in one. Seven are matching games (companies, animals, landmarks, food, cities, historical figures and basketball players), and three are guessing games: Best Guess, Ocean and Price tags. In a matching game, every day each has a new board of 8 items and 8 categories. Put each item where it scores best, and ride one wave at the game's own surf spot, a trick for every match.
The Daily Surf
Every day, three of the ten games are picked for everyone: the Daily Surf. Surf all three and their heats add up to one score out of 30 (three heats out of 10, added, not averaged), with one share and one streak, for the days you finish all three. The home page leads with them, and each of the three says “Daily Surf” at the top, with which one of the three it is.
The three are picked ahead of time, the same for everyone: two matching games and one guessing game every day, never a game two days running, and no game left out for long (a matching game sits out at most six days in a row, a guessing game at most four).
The other seven are Free surf: still a new board every day, with their own curve, streak and share, free to play any time. They just don't count toward that day's Daily Surf.

The matching games all play the same way. Each game has its own board, its own curve, its own streak and its own share.
How a day works
- You see the whole lineup of 8 items (companies, animals, landmarks, foods, cities, historical figures or players), each with a few words on what it is, and the 8 categories. Every game but the companies has a photo for each, too.
- The items go in the lineup's order. Tap an open category and the one up now is in, final, with no button to confirm and none to move on: the next one is straight up. Each category takes one item, so plan for the ones still to come.
- Each match scores 0 to 10 and is a trick on your wave; its popup shows the score and the item's actual figure. The results show every figure, and where each item would have scored best.
- After the eighth, the judges score your wave out of 10, the average of your eight tricks, set against the best heat the day's items allow and everyone who played that game today.
Scoring
The whole heat is one wave, and each match is a trick on it, scored out of 10. On one wave a miss can't end the ride, so a poor fit is a bogged turn and a 0 a big bobble. The better the fit, the bigger the trick:
- 10.0: Backflip or Air 360
- 8.5 to 9.9: Indy grab
- 6.5 to 8.4: Frontside air
- 4.5 to 6.4: Lip snap
- 2.5 to 4.4: Carve
- 0.1 to 2.4: Bogged turn
- 0.0: Big bobble
Every day's board, in every game, is dealt so a near-perfect heat is possible: each category has an item that fits it well, and the best possible heat is always 9.7 or better. Finding it takes planning, since the item that looks best for a category now may be needed somewhere else later.
At the end of the wave five judges hold up cards for the whole heat: its score, the average of the eight tricks. The highest and lowest cards are dropped, and the three in the middle always average to the score.
The guessing games
Best Guess, Ocean and Price tags each give you four questions a day, each with one true number. Type your best guess at each, plainly or in shorthand (1,250, 40k, $3.5M, 2.5 billion), and press Enter: it's in, and the next question is up. Each guess is a trick on your wave, and the judges score the heat out of 10: the average of your four.
A guess scores by how many times off it is, either way, so half the answer and double it are the same miss, and being 2× off on 300 is as close as 2× off on 3 billion. Every doubling costs the same, down to 0. The answers run from cents to quadrillions, so knowing the order of magnitude is the skill, and it reaches 0 at 10× off in all three:
- Best Guess: spot on 10.0, 1.25× off 9.0, 1.5× off 8.2, 2× off 7.0, 3× off 5.2, 4× off 4.0, 10× off 0.0
- Ocean: spot on 10.0, 1.25× off 9.0, 1.5× off 8.2, 2× off 7.0, 3× off 5.2, 4× off 4.0, 10× off 0.0
- Price tags: spot on 10.0, 1.25× off 9.0, 1.5× off 8.2, 2× off 7.0, 3× off 5.2, 4× off 4.0, 10× off 0.0
The categories
Each board uses eight of its game's categories. A category that counts doublings gives the same points for each one, so the step from small to twice as big is worth as much as the step from big to twice as big.
Companies
Each board uses eight of these 15. “Last year” means the company’s latest fiscal year, and “at year end” the last day of it. The money categories count doublings, so going from $2B to $4B in sales is worth as much as going from $50B to $100B.
- Sales: Sales in its latest fiscal year: 1.5 points for every doubling over $1.5B, so $6B scores 3, $24B 6, $96B 9, and about $152B or more 10. Under $1.5B scores 0.

- Sales per employee: Last year's sales for each employee it had at year end: 2 points for every doubling over $60K a head, so $120K scores 2, $240K 4, $480K 6, $960K 8, and $1.92M or more 10. Under $60K scores 0.
- Cash on hand: Cash and cash equivalents on the last day of its latest fiscal year (a bank's cash at the Fed counts): 1.5 points for every doubling over $200M, so $800M scores 3, $3.2B 6, $12.8B 9, and about $20.3B or more 10. Under $200M scores 0.
- Assets: Everything it owned on the last day of its latest fiscal year: 1.5 points for every doubling over $3B, so $12B scores 3, $48B 6, $192B 9, and about $305B or more 10. Under $3B scores 0.
- Inventory: Goods on hand on the last day of its latest fiscal year: 1.5 points for every doubling over $100M, so $400M scores 3, $1.6B 6, $6.4B 9, and about $10.2B or more 10. Under $100M, or none, scores 0.

- Buybacks: Cash spent buying back its own stock in its latest fiscal year: 1 point for every doubling over $10M, so $40M scores 2, $160M 4, $640M 6, $2.56B 8, and about $10.2B or more 10. Under $10M, or none, scores 0.
- Heritage: Years since the business was founded: 1 point for every 15, so a 75-year-old company scores 5, and 150 years or more 10.

Where the numbers come from
Companies
Every figure comes from the company’s latest annual report (its 10-K) filed with the US Securities and Exchange Commission, read from the filing’s own data, with employee counts checked by hand against the report’s text. Founding years come from the filings and Wikidata. Companies’ fiscal years don’t all end in December, so when a match is revealed, it says exactly which year the figure covers.
daily.surf is a game, not financial information: the figures are a snapshot of one year, and nothing here is investment advice.
Animals
Top speeds come from each animal’s Wikipedia article, checked against a source (the Animal Diversity Web, zoos, National Geographic, or a paper). Weight, record lifespan, how long young take to be born or hatch, babies at a time, and age at first breeding come from AnAge, the Human Ageing Genomic Resources database, checked against Wikipedia where it has no figure or disagrees. Endangered is the IUCN Red List’s rating. Most looked-up is the English Wikipedia article’s views in 2025, and Known worldwide how many languages Wikipedia covers it in.
The yes/no categories (flying, venom, night owls, breath holders, stripes and spots, and where it lives wild) were tagged by hand. Where the answer is arguable, like a chicken’s flight or a garter snake’s venom, the animal sits that category out.
Landmarks
Heights come from the list, checked against Wikidata: ground to highest point, a waterfall’s drop, a rock’s rise over the land around it. Altitude comes from Wikidata, or from Copernicus terrain data where Wikidata has none. Age counts from when work began on what stands today. Visitor counts come from the sites’ own operators, park services and tourism ministries. Temperature and rainfall are NASA’s climate averages for 2001 to 2020 where each landmark stands, and World Heritage is UNESCO’s own list.
The yes/no categories (the continent, a capital city, all white, seeing red) were tagged by hand; a landmark that can’t fairly answer one, like a mountain’s height or a natural wonder’s capital city, sits it out.
Food
Every nutrient comes from the US Department of Agriculture’s (USDA) FoodData Central, its SR Legacy data, per 100 grams of the food as it’s usually eaten, so a spoonful of salt and a bowl of soup compare gram for gram. Most looked-up is the English Wikipedia article’s views in 2025.
Where a food was first grown or made, and whether it grows on a tree, were tagged by hand; a food of disputed birthplace sits that category out. Wake-up call is caffeine, 1 mg or more per 100 grams.
Cities
Population, area, elevation, founding year and whether a city is its country’s capital come from Wikidata, for the city inside its own limits, not its metro area; density is population over area. Temperature and rainfall are NASA POWER’s climate averages where each city stands. Most looked-up is the English Wikipedia article’s views in 2025, and Known worldwide how many languages Wikipedia covers it in.
On the coast, Olympic host and the hemisphere were checked by hand. A city whose founding is lost to history sits the age category out.
Historical figures
Birth and death years and places, the things named after someone, the works that depict them or are about them, their awards, their children, a Nobel Prize and a crater named after them all come from Wikidata. Most looked-up is the English Wikipedia article’s views in 2025, and Known worldwide how many languages Wikipedia covers them in.
Someone still living sits out how long they lived and how far from their birthplace they died, and a figure Wikidata has no count for sits that category out.
Hoops
Height, weight, the draft, All-Star picks, titles, MVPs, the Hall of Fame, the 75th Anniversary Team and Olympic gold come from each player’s Wikipedia article, and every career average from the article’s own statistics table: the NBA regular season only, no playoffs and no ABA, through the 2025-26 season. Career points are games times points a game, so within a rounding of the official total. Birthplace and the Wikipedia counts come from Wikidata; Most looked-up is the English Wikipedia article’s views in 2025.
Steals and blocks were first counted in 1973-74, so earlier players sit those out, and territorial picks sit out Draft steal. daily.surf isn’t affiliated with or endorsed by the NBA or any of its teams, and uses no logos.
Best Guess
Every question was written from scratch, with one true number stated by a reputable source (a government agency, a science body, a company’s own report, a reference work), whose own sentence is kept with it. Each comes with a line of napkin math toward the answer, shown in the results. A few answers are a source’s “more than” figure, and a guess is scored against that figure.
Ocean
Every question was written from scratch, with one true number stated by a primary source (NOAA, NASA, the US Geological Survey, a science body, a peer-reviewed paper, a surf contest’s own records), whose own sentence is kept with it, and a line of napkin math toward it. A few answers are an “up to”, a “more than” or a paper’s estimate, and a guess is scored against that figure.
Price tags
Every price comes from a primary source: the agency or company that paid or charged it, the auction house that sold it, or a government statistics office (the Bureau of Labor Statistics, the USDA, the Energy Information Administration). Prices are in US dollars, as of the year the question names, not adjusted for inflation unless it says so.
The photos of the animals, landmarks, foods, cities and players, and the portraits of the historical figures, come from Wikimedia Commons, under free licenses or in the public domain. Each one's author and license are shown under it, linked to its page on Commons.
Questions
When do new boards come out?
Every day at midnight Pacific time, in all ten games at once. Everyone gets the same boards.
Do I have to play all ten?
No. The Daily Surf is today's three: play them in any order, and the home page keeps your running total out of 30. Its streak counts the days you finish all three. The other seven are Free surf, there whenever you want more; each game counts its own streak too.
Why don't I see a “Top X%” for the Daily Surf?
Each game's heats are stored apart, each under a different anonymous ID, so the stored scores can't be tied together into one player's three. Each game still shows where your heat placed among everyone's; the Daily Surf shows your total.
Can I play again?
Yes. Your first game on a device is the one that counts on that game's curve for the day; after that, “Play again (practice)” replays the board without counting.
Why can't I pick the order?
The lineup's order is part of the puzzle. You can see every item from the start, but each placement is final before the next one comes up.
What if an item has no figure for a category?
It sits that category out: an animal with no reliable top speed, a landmark whose visitors aren't counted, a yes/no question it can't fairly answer. Placing it there scores 0, and the reveal says so. Boards never deal a category without an item that can play it well.
How often does an item come back?
An item plays at most once in any 19 days in its game, and a board never has more than two from the same industry or group (two big cats, say, or two towers).
Which companies are in it?
276 well-known companies listed in the US, across tech, retail, finance, food, travel, health, and more. To keep the game for everyone, there are no alcohol, tobacco, gambling, or firearms companies.
Do I need an account?
No. There's nothing to sign up for. Your streaks and your games stay in your browser; see Privacy for what the site stores.
Is it free?
Yes. Ads keep it free, and they never cover the board.
I think a number is wrong.
