Stack Smith
Drop the sliding block to stack it as high as you can. Line it up cleanly to score big; miss and the overhang gets shaved off. Every few floors a question gives you a hand: slow the block down, snap it into place, or save one bad drop.

About Stack Smith
Stack Smith is a block-stacking game with studying worked into the climb. A block slides back and forth at the top; tap to drop it on the stack, and whatever hangs over the edge gets sliced off and tumbles away. Land one cleanly and your block grows back a little and you score a bonus. Every few floors a question shows up. Answer it right and the next block is easier to place; get it wrong and it speeds up.
