Okay is a free puzzle game with a straightforward idea but tricky puzzles. By bouncing a ball, you need to hit a set of objects. This sounds simple until you consider that you need to hit all of the objects with a single throw of your ball.

Behind its oddly generic title, Okay is best summed up as a game of virtual marbles, similar to Marbles On Stream and Marble Arena 2. The mechanics are basic, yet they accurately recreate real-world marble-bouncing physics.

Bounce the ball to hit the shapes

In Okay, the player controls a bouncing ball. Simply by touching the screen, you can choose where to place the ball and in which direction to launch it. Also on-screen are various white shapes. The objective is to make the ball hit all the white shapes in a single move to complete the puzzle.

New shapes make for new puzzles

The puzzles start simple but soon grow more complex through the addition of more elements. As well as new white shapes, you can expect to encounter indestructible black shapes, which must either be avoided or used to your advantage. Also appearing are white "strings" that must be hit, but they don't make your ball bounce.

A tuneful puzzler

Although its graphics are very basic, Okay manages to create a mellow mood through sound. It is designed so that each bounce of the ball produces a note, meaning that completing the puzzle results in a short tune. This is a minor touch, but it's one that helps give the game appeal.

Simple, fun, and for all ages

Players of all ages can get to grips with Okay. The gameplay is simple to pick up, but the many puzzles are tricky enough to keep players coming back for more. Children might have fun with the marble-bouncing mechanics, but adult players will appreciate the brainteasing aspect and relaxing tone just as much.
