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 given tiles on the blank spaces in the puzzle such that every sequence adds up to a multiple of five (5, 10, 15, etc.). The darker tiles are hints, fixed in place. It’s like a crossword puzzle of numbers!

There are 100 hand-crafted puzzles that start out simple and get more challenging as you go. If you get stuck you can tap the lightbulb button to earn an additional hint by watching a short video. If you prefer, you can also remove all advertisements completely with a one-time purchase on the Options screen.

You can also try the new random puzzle generator. You specify the size and the number of hints, and it generates a brand new puzzle, just for you! You'll never run out of new puzzles to play!

If you haven't played the Five-O board game yet, be sure to check that one out as well!

So far...

Only just started and at level 21 but definitely a fun game. I'm a numbers freak and love Five-0. Keeps me going for "just one more level"----aka quickly addictive.
