No. Free Casual mode works without any wallet — just open and play. A Celo-compatible wallet (MiniPay, MetaMask, Valora, etc.) is only needed for Paid Casual and PvP modes.
Both players stake 0.1 CELO before the match. After 10 questions, the player with the higher score wins 0.174 CELO (87% of the 0.2 CELO pool). The remaining 13% goes to the protocol treasury and contributors.
Royalties accumulate on-chain as Paid Casual sessions complete. Each session distributes 27% of fees proportionally to all contributors whose photos were used in that session. Payouts are claimable directly from your profile.
If both players score identically, the stakes are refunded minus gas fees. Ties are rare due to the tiebreaker: fastest correct answer wins the round.

Celo's fee abstraction layer (Mento protocol) lets you pay gas fees in cUSD instead of CELO. That means you never need to hold CELO just for gas — your stablecoin balance covers everything.
