Overview

Features & Capabilities

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.
*Hat tip to "A Thousand Brains" by Jeff Hawkins, you should buy this book.

User Reviews

So far it seems amusing. Every new game gives you 5 or 10 minutes (or a few levels) of uninterrupted gameplay at first though to get you hooked - Now that ads have been unlocked I'll update my review if they're excessive.

Saw this on reddit and I like puzzles so I gave it a try. It's really fun and I like the huge boom sounds from getting a one shot. Some of the more difficult puzzles, I didn't get a one shot but still I really like this game.
