Unique Pure Logic Brain Game!
Start a chain reaction that will clear all the O's from the screen -> ONO (no O's).
A new type of hybrid casual puzzle game. An overlapping maze. Like Sudoku without numbers. Wordle without letters.
Starting with the simplest forms + rules, complexity and variety emerge as elements are added in larger puzzles.
A fun easy way to work on your clarity, focus and working memory.
24 levels from very easy to very hard. Master each level by solving 4 puzzles - you are allowed three tries in each of the first two, two tries in the next and, finally, you must solve one puzzle in a single try. The level is then open for free play with three tries forever.
Skippable interstitial ads after every other level.
You can to watch a :30 reward ad to unlock a level or get additional stickers
Larger levels have 1000's of puzzle variations making ONO a game you can play over & over.
*Hat tip to "A Thousand Brains" by Jeff Hawkins for game inspiration, you should buy this book.
