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.
