Make room for a little logic. Pure Logic brings six puzzle games together: Sudoku, Nonogram, Binary Puzzles, Queens, Light Up, and Bridges. Explore different rules, choose your difficulty, and enjoy a puzzle at your own pace. SIX WAYS TO THINK Fill Sudoku grids, follow Nonogram clues, balance two symbols, place Queens, illuminate a board, and connect islands with bridges. A WORLD OF DETAILS Start with the warm Meadow theme. The optional Polar Crystal theme brings an icy setting, board skins and matching details to all six games. Discover Queen styles and illustrated Nonogram collections as you play. HELP WHEN YOU NEED IT Use hints and undo, continue saved puzzles, and adjust sound and haptic feedback separately. Your progress, collections and points are saved on your device. No app account is required. FREE PLAY AND OPTIONAL PURCHASES Sudoku, Nonogram and Binary Puzzles have no daily new-puzzle limit. Queens, Light Up and Bridges each include three free new puzzles per day. Replaying the same puzzle that day does not use another play, and continuing a saved puzzle is free. Queen Atelier challenges share the Queens allowance. Pure Logic Pro is a one-time purchase that removes these three games' daily new-puzzle limits. Polar Crystal is a separate one-time theme purchase. Pro does not include Polar Crystal; purchasing the theme does not change free-play limits. Local progress may be lost if you delete the app. Restore Purchases restores eligible purchases, not deleted local puzzle progress. Support: abc466254511@gmail.com
