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

Một đồng xu được tung mỗi vòng. Chọn mặt ngửa hoặc mặt sấp. Nếu bên bạn chọn xuất hiện, bạn sẽ vào vòng tiếp theo.

NGỬA — the coin lands face upvsSẤP — the coin lands face down

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

Mỗi giải đấu gồm nhiều vòng. Trong mỗi vòng, bạn phải đưa ra một dự đoán nhị phân. Nếu đúng, bạn đi tiếp vào vòng sau. Nếu sai, bạn bị loại.

Giải đấu tiếp tục cho đến khi chỉ còn lại một người chơi. Người chơi đó sẽ giành toàn bộ giải thưởng! Nếu sau số vòng quy định vẫn còn nhiều người chơi, giải thưởng được chia đều.

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.
