Read shapes as well as colours
Cherries have a paired fruit shape, Lemon a single citrus silhouette and Grapes a clustered outline. Bell, Seven and Coin offer three further distinct forms. The interactive board supplies their names in addition to the illustration.
A different decorative finish does not create another type. All copies of a Bell belong to the Bell identity, whether shown on a reel, reference picture or collection stamp.
Understand what earns a stamp
Two equal symbols on the chosen route produce two point counters and one matching stamp. Three equal symbols produce four counters and one stamp. A route with three different identities produces only one counter.
The two equal symbols can be separated by the third space. Their position does not reduce the award as long as all three spaces belong to the same selected row or diagonal.
Build a useful set of identities
At the close, every different stamp identity adds two points. Four stamps showing Cherries, Bell, Cherries and Seven therefore represent three types. Counting all four as separate types would overstate the bonus.
The puzzle room sometimes names a target identity so you practise finding a specific match. That learning objective does not change the ordinary game's scoring scale. It simply focuses attention on a legal result already available from the board.
