Kopak app for iPhone and iPad

The rules are simple. Clear all cubes by passing over them. Easy to learn but be prepared for a big brain workout!

Explore 50+ levels that will push your problem solving abilities.

Gameplay:
Moving one cube at a time either vertically or horizontally, you must clear all cubes to complete the level. To remove some cubes, you need to pass over them twice, some requiring 3 passes. You also have blockers that prevent you from passing.

As the levels increase, the harder the puzzles. One wrong move and you will have to start the level again, so thinking 3 steps ahead at all times is a must.

Once you have completed the 50 standard levels, you can check out the extra levels that will be updated with new levels regularly.

Engaging in mental activity through games and puzzles can help keep the mind sharp in old age. Just as regular physical exercise helps the body, regular mental exercise has benefits for the mind. Completing games like Kopak have been shown to be beneficial to the maintenance of short-term memory, eye-hand co-ordination and general concentration.
