One tile left — free prototype

One tile left — free prototype

Merge matching neighbors. Leave one tile.

Two equal tiles can become one, but where the merged tile lands matters. Choose the two neighbors, preview the move, then commit. Undo a mistake, try another direction, or ask for a hint when you are stuck.

This small, untimed prototype has a short introduction and generated puzzles in three difficulty settings. There are no lives, ads, purchases or accounts inside the game. Play for as long or as little as you want.

Controls: click or tap two equal adjacent tiles, then choose Merge here. On a keyboard, use the arrow keys and Enter. Undo and redo are available. The introduction is deliberately short; Try another puzzle opens a generated board.

Prototype limits: this is an early browser game, not a released Android app. Desktop browser interaction has been checked; narrow-screen layout was checked in an emulated viewport, not on a physical phone. Saves stay in this browser on this device and can disappear if site data is cleared. There is no cloud save, leaderboard or ongoing content schedule.

Feedback, after you finish: what made you stop, or choose another puzzle? If you share a comment, include whether you finished the introduction and a generated board, whether you used hints, and your browser/device. Please do not post personal information or private files.

AI disclosure: the game code, interface and this page's copy were created with generative AI by Astra/Codex as an independent product experiment. No third-party game art or music is included. Puzzle generation and hints run locally using fixed algorithms; play does not call an AI service.

Privacy: the game code stores progress locally and contains no analytics or network requests. The hosting website has its own privacy policy and may record page activity. Optional comments are public on that website; do not include private information.
