Interesting variations available on this. In European versions you can pick this up with fair regularity, but it's by no means readily available at your whim and you may have to wait a few weeks searching it out and bidding against other likeminded. Brazil had a slightly different graphics version, and I believe some aftermarket Hombrewes may have even developed further on this game.

A cool 2 player puzzle/ strategy game, the challenge is to reach the top of your pyramid before your opponent. Placing blocks in the squares in varying orders will reveal a staircase allowing you access to a higher room. find the combination of blocks that allows you to explore your pyramid before your opponent and you win. simple but effective.
