ONO: Think Straight

Fun Fast Puzzle Game

A brand new kind of puzzle game that relies on your most basic brain functions - motion and prediction. Below the words of Wordle. Beneath the math of Sudoku.

Start a chain reaction that will clear all the O's from the screen -> ONO (no O's). A fun easy way to work on your clarity, focus and attention.

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. Ads only required for bonus rewards: You have an opportunity to watch a :30 ad to unlock a level or to get 2X points to help you run up your score. Larger levels have 1000's of puzzle variations making it a game you can play over & over.
