GatherReserve

Build a calm, focused number puzzle habit with an offline board that rewards planning. Slide the whole board in four directions. Matching neighboring tiles merge into a higher value, while every valid move places a new tile in an open space. Every move matters: protect room, guide your largest tile, and keep future merges available. Classic mode is an open-ended test of score and tile value. Challenge mode adds 50 fixed, replayable starting boards with clear targets, so success comes from a plan rather than an unexplained random outcome. Reach the target, or keep going to improve your board. Useful play features include: • A dedicated home screen with quick access to classic play, levels, challenges, statistics, and guidance. • One undo for the latest move, restoring the board, score, and generation sequence together. • Saved boards that remain available when you leave and return later. • Clear score, highest tile, move count, goal progress, pause, and end-of-board summaries. • A practical guide explaining movement, one-merge-per-move rules, tile generation, and ending conditions. • Adjustable swipe sensitivity, merge animation, sound feedback, number size, and assistive texture preferences. All gameplay and progress are designed to work locally without an account, network connection, advertising, payments, or a leaderboard. Your board and preferences stay on your device.
