Stackward: Block Puzzle

Stackward is an 8×8 placement puzzle with rows, columns, and 4×4 quarters, 200 designed and solver-proved campaign levels, a server-replayed Daily, one-board continuous Endless, and a separate Gauntlet of proved rounds. It includes blockers, objective variety, free retries, free Endless rerolls, drag/tap parity, themes, high contrast, left-hand layout, and three motion levels. It has no ads, lives, energy, consumable currency, paid retry, or ranked purchase advantage.

Free, forever: today's ranked Daily, with no account needed to be ranked; the first 20 designed levels; three score runs a day, shared by Endless and Gauntlet; one undo per level; and the complete tutorial.

A one-time Stackward unlock opens all 200 levels, unlimited score runs, the complete Daily archive, unlimited non-ranked undo, solver-backed hints, and advanced records.
