One disc always represents one point
Take coins from the shared supply only when resolving a turn. A three-different-symbol pattern takes one, a matching pair takes two, and three matching symbols take four. All discs have the same value regardless of their position in a stack or their decorative finish.
There is no entry cost and no balance to spend before turning a reel. A player cannot buy another shift, exchange coins for a Strike card or risk an existing stack on the next pattern. Collected coins remain in that player's scoring area.
Separate the immediate award from the collection
The coin award and symbol seal are two parts of the same result. A pair or triple receives its stated coins plus one seal. Place both in view before the next player starts so the table can verify the count and the type of seal earned.
The Coin emblem on a reel is a symbol, while a small point disc in the supply is a score marker. Matching Coin symbols can earn a Coin seal under the normal rules. Merely seeing an individual Coin emblem does not grant a separate payment.
Use a clear replacement if the supply runs short
The exact number of manufactured discs is not important to the concept. Use written tallies or other distinct one-point markers if a physical prototype needs more counters. Announce the substitution and keep the same values, rather than changing the awards halfway through a game.
When the sixth round closes, count each player's coins once. Add collection variety and any unused-Strike point separately. The scorebook provides a worked example and a small calculator for checking that final sum.
