Stacko is a game of the mind. A game of the soul. A game of the spirit. OK, maybe not, but it does involve the mind. It's a puzzling brain-teaser that will have u thunking really hard once u get past the easy levels.
Your objective is to get the colored blocks to stack up in the right order, as shown in the objective window on the game screen. Get it right and u will be rewarded with stars and the opportunity to repeat the process on the next, more difficult, level.
It may appear random at first, just clicking here and there and then getting the right result... but there is madness to the method here.
