What players say
@makeriffic · loved it · 2026-10-11 · played under a minute: “I love how fun and very educating this game is. Fun in terms of surfing curves. And educating in terms of mathematical problems. I like how simple and complex those questions could get.”
@lego · needs work · 2026-10-10 · played 18 min: “Fun CS surfing game! I suck at this tho haha. Btw the ramps are blocking the answer numbers, so it's hard to see which one to pick”
@kaya · loved it · 2026-10-10 · played 13 min: “i used to play a lot of surf games in CS before and this was quite unique lol. had to use my brain and keyboard at the same time just to get the perfect run. would be great though if there was a hard reset button where you could go back to 0.00s.”
