Train your brain! And definitely strain it.
Test your brain’s capacity by climbing as far up the tower as possible. Memorize the pattern of correct tiles to get to the top.
Much like the card-flipping game Concentration, you must memorize the backs of the cards to get to the next row. Flip over an incorrect card and you will be sent back to the bottom.
Try all 3 different modes!
Compete against the clock in Speed; against mistakes in Accuracy; and against the limits of your memory in Capacity.
