KIPP X

Will the game board tip down or not? That's the question players face each turn in KIPP X, a captivating and challenging balance game that's yet easy to play. Just place a wooden block on the cross-seesaw and that's it – if it were not for the tipping.

To win KIPP X, you must be the first to get rid of all your blocks. To do this, you carefully position them one at a time on one of the lifted-up halves of the cross-seesaw. At some point, however, the weight becomes too much and the cross-seesaw tips down. If this happens, you must take any block(s) that fall off. Thus, you can't be too bold when placing blocks on the upraised planks – but maybe you can place just one more block...
