About this game Read the full description
In this Kakuro-inspired puzzler, you're on a number budget. Try your hand at mastering these simple digits in this colorful, upbeat puzzler.

Your goal is simple: combine numbers in their respective rows or columns until all the conditions are met. Will you be able to handle all the tricks waiting in store?

What to Expect:
  • Solve 100 math puzzles, but you can only use the numbers 1-9 once apiece; it can be trickier than it looks!
  • Jump from puzzle to puzzle with ease: your work on unsolved puzzles is saved so you can come back to it later.
  • Discover interesting gameplay wrinkles as you move between each tantalizing puzzle set.
  • Choose between six vibrant themes, or use the blank "minimalist" theme if you want maximum concentration.
  • Enjoy a musical score that evolves as you play the game, or keep it at "ambient only" to keep things more relaxed.
