About 11111Game

11111Game is a tile-merging puzzle game in which you slide tiles on a grid and combine them by addition. Make a specific number to score, using the blank space in the middle and the overflow mechanic to shape your moves and avoid scoring randomly.

Different number bases

The game explores addition in different bases, including less common ones, where the result of a sum depends on the base being used.

Levels and skins

Complete levels to unlock new skins. There is no time limit, and the game includes chill music.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
