Make space, read the board, and choose your next move with care.

This offline number puzzle is built around thoughtful movement rather than speed. Swipe the board in four directions to slide every tile together. Matching neighbors merge into a higher value, while each new tile gives you one more decision to make.

Classic mode is an open-ended score chase. Target Challenges add 50 fixed openings with clear goals and repeatable starting positions, so a failed attempt teaches you something useful instead of depending on hidden randomness.

Each round includes:
• A 4x4 board with readable number, brightness, and texture cues
• Strict one-merge-per-tile movement rules
• Local score, move count, highest tile, and unfinished-round recovery
• One-step undo that restores the board and score together
• A pause screen and a recap with your best tile and board summary
• Preferences for theme, animation, sound feedback, number size, and swipe sensitivity
• A compact play guide explaining movement, merging, space, and end conditions
