What’s New Version 2026.04.20

More puzzles between ads. Less ads. More fun. Added exit to menu button in puzzles. Fixed embarrassingly overlooked errors.

Description

Fun! Fast! Free! Unique Bedrock 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.
