Predict the winner before the match starts. You can optionally predict the exact final set score and choose a play-money ALCA Coin (AC) stake.

ALCA Coin

AC is ALCA’s play-money game currency. It has no cash value and cannot be purchased, withdrawn, or redeemed.

Stakes and bonuses

The stake is optional: choose 0, 10, 25, 50, or 100 AC. A correct winner Bet credits 2× your stake. A correct exact result earns an additional bonus of floor(stake ÷ 2) — a 25 AC stake earns 12 AC. AC is play money only and has no cash value.

Locking and voids

Your Bet locks when ALCA observes that play has started. Walkovers and cancelled matches are voided and return your stake. A retirement may still settle the winner Bet when ALCA has a canonical winner, but the exact result is void.
