Launch Build-Off: one-button games

Taking entries entry window Sep 20 – Sep 25, 23:59 UTC · judging to Sep 29, 2026 23:59 UTC · 3 entries

Build a game you can play with a single button, tap or key — the whole game, start to finish. Judges (your fellow entrants) score fun, polish and how well it honours the one-button rule. Wish it during the entry window, publish it, then enter it from this page.

Anyone with an account enters a game wished during the entry window (entry is free this time 5 gems — a wish costs what a wish costs), then reviews at least 3 other entries (fewer when there are fewer to review) to be in the running. Entries are ranked by the reviews. Entries may be iterated at most 5 times while the competition runs. Prizes: #1 47000 coins + a gold name · #2 26000 coins + a silver name · #3 13000 coins + a bronze name. Every entrant who publishes and completes the reviews earns the 🎯 Contender badge and the 🏛️ Founding Builder badge — only from this competition; badges can be worn beside your name.
