Questions and answers

Updated October 2026

What is SpermRace?

A browser game. Everyone starts together in an arena. Your cell leaves a trail behind it, and touching any trail, yours or someone else's, puts you out. The arena gets smaller over time. The last cell still alive wins. A match takes about 2 minutes.

How do I steer?

• Computer: your cell swims toward the mouse pointer. The WASD or arrow keys also work. Hold Space or Shift to go faster. Press Q for your ability (a short shield until you pick another class).
• Phone: drag on the left half of the screen to steer. Hold the Boost button to go faster. Tap the ability button (a short shield until you pick another class).

Is it free?

Free practice is always open: you against computer players (bots), no wallet, no sign-up, no money involved. Your first matches have only 3 to 5 bots and a gentler arena; from the fourth match it is the full field of 7.

How do paid rooms work?

• Paid rooms have up to 16 players. Each player pays the same entry fee: $1, $5, $25 or $100, paid in SOL, the currency of the Solana network.
• The winner gets 85% of the entry fees players paid. The other 15% is the platform fee. Only 1st place is paid.
• A room that is not full can include bots. Bots pay nothing and add nothing to the prize, so the prize grows only with real players. The amounts on the home page ("up to $68") are for a room where every seat is paid.
• Paid rooms open once a day for a fixed time window. The home page shows when the next one opens.

What do I need to play for money?

A Solana wallet app, for example Phantom, with enough SOL for the entry fee and the network fee. You must be 18 or older and allowed to play skill games with prizes where you live. See the Terms for the excluded places.

How is the winner paid?

Automatically, on the Solana blockchain, a few seconds after the match ends, to the wallet you joined with. Every payout is a public blockchain transaction you can look up.

When do I get my entry fee back?

• If a room is cancelled before the match starts, for example because no other player joined in time.
• If the match ends in a draw: every remaining cell is out at the same moment.
• If our server stops during a paid match: when it restarts, everyone in that match is refunded.

Refunds are sent automatically to the wallet you paid from, minus the Solana network fee (5000 lamports, a tiny fraction of a cent).

What if my connection drops during a paid match?

You have 10 seconds to come back: reconnect or reload the page and you rejoin the same match. After that, you count as out, the same as being eliminated.

Is it gambling?

No. The result depends on how you play, not on luck. Practice is free so you can learn before you pay anything.
