Build a stack of steps that reaches the flag — exactly. Tap + to load a block, then Go!. The bulldozer glides your blocks up the ramp onto the stack, and Raja climbs up.
Too few? Raja can't reach — a dashed gap shows how many more you need. Too many? The blocks shoot past the flag. No score, no penalty — just adjust and try again. ↑/↓ add/remove, Enter go.
