Live collaboration; no fixed game-seat cap
Set up the table
Choose three to eight disks; five is the default. They begin on the left rod, largest at the bottom. The middle and right rods are empty. This real-time game has no fixed game-seat cap; that does not imply unlimited infrastructure capacity.
On your turn
Select a top disk, then choose a rod. Move one disk at a time onto an empty rod or a larger disk. A held disk is reserved temporarily so two people cannot move it at once; finish or release your selection before grabbing another.
Winning and ending
All disks on the right rod complete the challenge. There are no alternating opponent turns.
Worked example
For three disks, label rods A (left), B (middle), C (right). Move A→C, A→B, C→B, A→C, B→A, B→C, A→C. The tower finishes on C in seven moves.
A common mistake
Never place a larger disk on a smaller one, even if another route seems longer.
Questions at the table
Can I choose a buried disk?
No. Only the top disk of a rod can be selected.
Does dropping back on the same rod count?
No. It releases the disk without adding a move.
