Queens by JL-Forge

A minimalist puzzle that grew on chess players and Sudoku fans alike. Place one queen in every row, every column, and every coloured region — but never two queens that touch, even diagonally. The board changes every game: random sizes from 5×5 to 11×11, shuffled regions, three difficulty levels. FEATURES • Random puzzles every game; never the same twice • Six smart hint detectors that explain WHY a move is wrong, not just THAT it is • Three difficulties (Easy, Medium, Hard) with adjusted region cohesion • Score formula that rewards speed and economy on hints • Personal records per grid size • Tap-cycle controls (empty → mark → queen) plus drag-to-mark • 40-step undo if you change your mind • Multi Language support • Dark, focused interface designed for one-handed play • Optional hint top-ups and ad-free upgrade; both completely optional A puzzle by JL-Forge.
