2–8 players, fixed elimination house rules. Each round the server uniformly chooses a secret integer from 1–100, unknown to everyone. Take turns in seat order choosing an integer within the inclusive current range. A low guess raises the lower bound to guess+1; a high guess lowers the upper bound to guess−1. Hitting the secret eliminates that player. The next surviving seat starts a fresh round with a new 1–100 target. Last player standing wins immediately. No stakes, prizes or paid items.

Rooms expire 24 hours after the last action. Refresh to reconnect; leaving ends the current game.
