About

Stackbound

Features
Read full description

Stackbound is the block puzzle that finally gives you a reason to keep playing. Drop blocks on a 10x10 grid, clear rows and columns, and chain combos for huge scores - then turn every game into a roguelike run. Every few line clears you draft one of three relics: refill cleared columns, triple every fifth clear, bank gold, and dozens more that stack into wild combos. Survive deep enough and a boss floor appears, bending the rules with locked cells, shorter racks, or score taxes you have to play around. No two runs feel the same. A daily seeded run gives everyone the same board, so you can chase the top of your local leaderboard. Between runs, persistent meta progress unlocks new relics and grid skins that carry forward - the deck of possibilities grows the more you play. FEATURES - 10x10 block puzzle with satisfying row and column clears - Roguelike runs: draft relics, build synergies, push your score - Boss floors every ten floors that change how you play - Daily seeded challenge with a local leaderboard - Persistent meta unlocks: new relics and grid skins - Endless mode for a relaxed score chase - One-handed portrait play, dark mode, and Dynamic Type support - Play free, or unlock Premium once to remove ads forever and open every skin and bonus relic slot Free to play with optional ads. Go Premium with a single one-time purchase - no subscriptions.

Verdict

The call

The clearest difference is in-app purchases: Sudoku at none against Stackbound's 1. Sudoku also leads on ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.
