Start with a common vocabulary
Name the three columns, both movement directions and five legal routes before the first round. Keep a reference card visible so a player can point to a diagonal rather than struggling to describe it under pressure.
Explain that the Coin emblem is a collection identity and ordinary counters are points. This distinction prevents a familiar picture from being mistaken for an automatic extra award.
Share access to the mechanism
Place the rack where all seats can see the windows and inspect their trays. A player may state a decision while someone else turns the wheel. Physical assistance does not change whose turn or collection it is.
Keep each person's Strike card in view. One used card should not obscure another player's unused card, and no shared pile should make ownership uncertain.
Maintain the full round structure
Play clockwise from the same agreed first seat through six complete rounds. A larger group creates more turns around the table, but it does not change the six-turn entitlement of each player.
After every award is checked, make a clear handover before the next adjustment. At the finish, sort the stamps by identity and apply the same arithmetic to all trays. Any house variation should have been agreed before the first movement.
