It’s a pachinko board and dice tower! Drop a d20 into the bucket at the top, and it’ll drop down below, bounce around, then land on one of the 20 tiles at the bottom.

From testing, landing on the first and last tiles are the least common results, whilst the others are somewhat evenly distributed.

Works best with 1 die, with only a low chance of getting stuck. Multiple dice dropped at once may clog the chute.
