Below the words of Wordle. Beneath the math of Sudoku.
Start a chain reaction that will leave no O's on the screen (O=NO).

HOW TO PLAY
You solve a puzzle by choosing the O that will cause a chain reaction that will destroy all the others. Master each level by solving four puzzles — you are allowed three tries in each of the first two, two tries in the next one and, finally, you must solve one puzzle in a single try.
The level is then open for free play with three tries forever. You have an opportunity to watch a :30 ad (or remove ads for .99) to get 2X points on this level to help you run up your score.
Locked levels can be unlocked early by watching a video ad.
Larger levels have 1000's of puzzle variations for endless play.
