Coverlet vs Quadrivium

A little logic. A growing quilt. Coverlet brings eight puzzle techniques together in a calm quilting-inspired game: Patchwork, Appliqué, Piecing, Stitchline, Rosette, Buttons, Cross-Stitch and Gingham. Explore a journey for every technique: 100 Patchwork levels and seven 12-level campaigns with progressive boards. Return for daily puzzles, the weekly Sampler Square, or a short Sprint. Play at your own pace. Relaxed campaign play is the default, with optional timed challenges and earned Thread rewards. Use hints and undo as you learn each technique. Core puzzles work offline. Start with the free boards. Full Quilt is a one-time purchase that includes the complete Patchwork Journey, board packs, the daily archive, unlimited practice and additional fabrics. Individual board packs remain available separately. Your existing purchases keep their benefits, and Restore Purchases is available in the app. No ads. No subscription. Optional Game Center features let you take your puzzles further.

Four logic puzzles on one square grid. Futoshiki, Skyscrapers, Magic Square and Calcudoku share the same board. In three of them every digit appears once per row and column, and the Magic Square uses every number exactly once. What differs is the clue around the grid: the signs between two cells, the numbers along the edge, the sum of every line, the target of a cage. Every puzzle is generated when you start it. You choose the size and the level, and for Calcudoku also which operations appear and how large a cage may grow. The hint never leaves you stuck. It names the rule that applies right now and shows the cells it applies to. Every puzzle the app builds can be solved with the techniques of its own level: no guessing, no dead ends. A daily puzzle, one puzzle type per weekday. Statistics, achievements, ten color worlds, and a newspaper world of its own on iPad. No account, no ads, no tracking. What you play stays on your device. I build this on my own: every rule, every hint, all 45 languages, one desk. No studio behind me, no ads, no tracking, no subscription. Write to me and a person answers. Happy puzzling, Tobias
