Watch duplicate ranks collect.
Perpetual Motion uses all 52 cards, four tableau piles, and a stock. Each action is prescribed: deal a four-card row, merge matching exposed ranks, discard a completed group of four, or recycle the tableau after stock exhaustion.

How one round advances
When exposed pile tops share a rank, the game moves duplicates to the leftmost matching pile. Four matching cards together at a pile’s top leave for the discard. Those actions take priority over dealing the next row. When the stock empties, remaining tableau cards are gathered into a new stock in a fixed order.
For example, if two exposed tops are both 6s, the required merge moves the right-hand 6 onto the left-hand 6. If that creates four 6s together, discarding the group is the next action. There is no alternative destination for the right-hand card.
How the game ends
Discarding all 52 cards wins. A repeated stock order is detected as a loop and ends the attempt. Because the move list contains at most one prescribed action, replaying the same seed follows the same sequence. Clock is also forced, but follows card ranks through a thirteen-pile dial rather than cycling four piles.
