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
毎ラウンド、コインが投げられます。表か裏を選択。当たれば次のラウンドへ。
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
各トーナメントは複数のラウンドで構成されます。各ラウンドで二者択一の予想をします。予想が当たれば次のラウンドへ進み、外れれば敗退となります。
トーナメントは、プレイヤーが1人だけになるまで続きます。最後に残ったプレイヤーが賞金プールを獲得！規定ラウンド数の後に複数のプレイヤーが残った場合、賞金は均等に分配されます。
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.
