GatherSpace

Make space, pair matching tiles, and keep your next move open. This offline number puzzle is built around deliberate movement. Swipe the 4x4 board in any direction and every tile travels together. Matching neighbors merge once per move, then a new base tile appears in an open space. A full board is not the end if a merge is still possible. Choose a mode for the way you want to play: Classic mode is an open-ended run toward 2048 and beyond. Watch your score, highest tile, effective moves, and largest merge while you search for a stronger board. Challenge chapters use repeatable starting layouts with clear tile goals. Practice the same opening, protect useful corners, and complete the objective without relying on an unexplained online service or random result. The board supports one-step undo, including the score and generated tile state. Pause safely, review a finished run, and start again when you have a new plan. Your current board and results are saved locally so you can return to the puzzle later. The guide explains movement, one-merge-per-swipe rules, tile generation, and end conditions. Preferences let you tune swipe sensitivity, animation, sound feedback, number size, tile textures, and theme. There are no accounts, ads, payments, online rankings, or required network features. Your play is designed to remain on your device.
