Fivefold

Fivefold is a Sudoku-inspired game where the rules change every puzzle. Fill the grid through pure deduction, combining familiar number-placement logic with new rules. It's a game that will never stop giving you those satisfying "Aha!" moments. Enjoy the daily puzzle with your morning coffee, or play a quick, easy puzzle while you're waiting for an appointment. When you're ready, you can move to harder puzzles, like our large 7x7 puzzles that'll give your brain a real workout. We kept Fivefold simple. There are no ads interrupting you, no in-game currencies, and no tricks to keep you playing. The game comes with a ton of free puzzles, and if you want even more, you can buy a puzzle pack. That’s it! We made Fivefold because we love puzzles too. We hope it makes your brain work just a little bit harder, and we hope that you’ll enjoy playing it as much as we enjoyed making it! - Matt & Owen
