Stack Tower

The story

A crane holds a block over the tower and you press Drop to let it go. If it holds, a new floor goes up and the prize grows. If it slips, the round is over. The first block holds 95% of the time, the fifteenth only half the time, so every floor is a fresh decision. Take the prize after any floor, or build all fifteen for x98.41.
