Coin Flip Tournament — Online Prediction Game
Call HEADS or TAILS every round, outlast the field, and win the crypto prize pool — a skill-and-prediction game, not a spin-the-wheel casino mechanic.
What is Coin Flip?
Coin Flip is one of Knockout.Global's prediction tournament game modes. It's the purest possible call: a coin goes up, and before it lands you commit to HEADS or TAILS. Every round you lock in one binary prediction before the timer runs out.
It's built for anyone who wants the classic heads-or-tails prediction game without the coin toss being a private joke between two people — instead it's run as a live, provably-fair elimination tournament with a real crypto prize pool on the line — not a slot machine, not a house-edge casino game.
How a Round Works: HEADS or TAILS
매 라운드 동전을 던집니다. 앞면 또는 뒷면을 선택. 맞히면 진출합니다.
Every round is a fresh 50/50 call, resolved by a hardware-seeded, provably-fair random outcome — the outcome is never influenced by anyone's prediction history, streak, or stake size.
Coin Flip Tournament Format
각 토너먼트는 여러 라운드로 구성됩니다. 각 라운드에서 이지선다 예측을 해야 합니다. 예측이 맞으면 다음 라운드로 진출하고, 틀리면 탈락합니다.
토너먼트는 단 한 명의 플레이어만 남을 때까지 계속됩니다. 그 플레이어가 상금 풀을 차지합니다! 정해진 라운드 수 이후에도 여러 플레이어가 남으면 상금은 균등하게 분배됩니다.
Coin Flip tournaments run as Quick Fire (fast, a few minutes), Daily Showdown, and High Roller formats — pick the pace and stakes that suit you, or join for free in Ghost Mode.
Provably Fair — Every Call, Verifiable
Every HEADS/TAILS outcome is generated with hardware-seeded RNG and a SHA-256 commitment published before the round opens, so no one — including us — can know or change the result once predictions are locked in. After the round resolves, you can independently verify the outcome yourself.
