FAQ

Common questions

Can I practice without signing in?

Yes. Every game has free practice. Sign in only when you want to compete for a prize pool.

What is KOIN?

KOIN is your balance in the platform. Their value stays fixed: 10 KOIN = $1 in USDC or USDT. They are an internal balance, not a tradable cryptocurrency.

What is Bonus?

Bonus is free entry credit — your ticket into tournaments with no deposit. Clear quests to earn it, or skip the grind: a weekly or seasonal pass gives you unlimited entries. Bonus cannot be cashed out.
