Gridzle: Grid Logic Puzzle

Gridzle is a counts-first grid puzzle for players who love pure deduction. Place geometric pieces onto a grid — every placement toggles the covered cells between filled and empty. Read the visible row and column count targets, plan the order of your moves, and solve each level by logic alone. No randomness. No trial-and-error grinding. Every puzzle is hand-designed and solver-certified. ★ WHY GRIDZLE STANDS OUT ★ • 250 hand-crafted levels across 5 difficulty tiers — from newcomer to master-class deduction • Deterministic solver-certified — every puzzle is proven to have a unique logical solution • Toggle mechanic — placements flip cells on and off, so order-of-operations is part of the puzzle • Buttery-smooth 60fps shape dragging with sub-16ms input latency • Dark neon aesthetic — premium visual polish, easy on the eyes • Offline-first — full gameplay works without internet, ever • Portrait-first — comfortable one-handed play on any commute ★ HOW TO PLAY ★ • Each level shows a grid with target counts for every row and every column • You receive a set of geometric pieces (polyominoes) to place • Drop a piece: every cell it covers toggles (filled becomes empty, empty becomes filled) • Solve when every row and column hits its target count It sounds simple. It plays deep. Order of placement matters — a piece dropped early can be toggled back by a later piece. The best Gridzle solves feel like elegant little proofs. ★ DESIGNED FOR LOGIC PUZZLE LOVERS ★ If you enjoy Hexcells, Picross, Nonograms, Sudoku, Flow Free, or any thoughtful deduction game, Gridzle will feel instantly familiar — and fresh.
