A new challenge for puzzle lovers – from the creator of the numerical board game hit Five-O!
If you've played Five-O, you'll find the rules to be simple and familiar. Just arrange the tiles onto the blank spaces in the puzzle so that every sequence adds up to a multiple of five (5, 10, 15, etc.). The puzzles start out with a set of dark tiles that are locked in place. It’s like a crossword puzzle of numbers!

There are 100 hand-crafted puzzles ranging from easy to extremely challenging. But don't worry! If you get stuck, you can tap the lightbulb button to earn a hint.

You can even create brand new puzzles to play yourself! You choose the size of the puzzle and how many starting tiles to reveal. You'll never run out of new puzzles to play!
