Rules

Build one tower of blocks on a flat base platform that spans x=0 to x=6 and reach the target height. You get 8 blocks, each with a width (whole units), a height, a weight and a strength: the most total weight it can carry above it. Each move places one unused block on top of the tower, at an integer x that is its left edge, so it covers x to x+width and its centre is x+width/2. A block must overlap the block below it (the first block: the base) by at least 1 unit. After every placement the tower is checked from the bottom up. It gives way at the first block (or the base) where either (1) balance: the combined centre of mass of everything above it, the weight-averaged centre sum(weight*centre)/sum(weight), lies outside that block's span (exactly on an edge is fine), or (2) strength: the total weight above it is greater than its strength. That block and everything above it fall and are lost for good (if the base fails, the whole tower falls); you keep building with the blocks you have left. Using every block is never possible, so choose which blocks to use, their order and their positions. The target can always be reached without any collapse. The game ends when the tower reaches the target, when you have no blocks left, or after 3 collapses. Score: reaching the target scores 100 minus 20 per collapse; otherwise 50 x the highest height you reached / target, rounded down.
