The object is to remove all of the blocks by tapping at an intersection that joins like-colored blocks.
Cross Blocks combines sequential movement with other elements.
For example: 2 blue squares right next to each other - impossible to eliminate them at the same time. Also, it's possible to eliminate 3 of the same color all at once- provided they form a T junction.
I solved all of the levels in the A world and B world pretty quickly. Then I purchased the additional levels. I particularly liked D-16. And I'm still stuck on D-19. Altogether, there are 80 levels and I've done about 65 of them. I tend to do these when I wake up and cant go back to sleep.
