By Opalin Play
A papercraft block factory where every win makes its cell worth more.
Five or more bricks of one colour pay, leave the board and double the cell under them. New bricks fall into those cells, so a good round keeps getting richer. Multiplier stamps can land before the count, and a full hopper drops a giant block over the whole board.

Costs are multiples of the base bet. Every mode has the same RTP: 96.35%. A bonus from the menu starts on the next SPIN, with a single debit.
MASTERPIECE
Masterpiece costs 1,000× the base bet. It plays 10 free rounds; every cell starts at ×16.
Cell multipliers stay between rounds, double with each win and gain +1 per Charge, up to ×256. They reset to ×1 when the bonus ends.
In 2 to 5 of the rounds, a complete figure is placed on the starting board, the first within the first 3 rounds. A figure pays its fixed value times the average multiplier of its cells: here, at least 16 times its value.
The Rocket only appears on a board where its cells average at least ×25: it then awards the maximum win, 50,000× the base bet, and the bonus ends.
No extra rounds can be won. The bonus ends after 10 rounds or when the maximum win is reached.
