The Set Builder allows you to choose the Things you prefer to play with. Sets you create may be used in Practice and Friendly games.
For each Thing you own, you can assign it one of the following values:
Always try to include (the checkmark)
Never include (the "X")
Priority from 1-5 Stars
This is shown graphically below each creature.
As shown, the Amazon will never be chosen, the Basilisk will always be chosen, and the Aqueduct has 3 Stars, so it will be chosen more often than other Things with less Stars.
The method for choosing Things is as follows:
Remove all Things with "X"s from consideration.
Choose randomly from Things in the set with checkmarks until enough Reserves have been chosen.
If there is room in the Reserves, each Starred Thing puts "tickets" into a virtual hat equal to the number of Stars it has. Then a ticket is picked randomly from the hat. The Thing's whose ticket was picked is added to the Reserves, and any of its remaining tickets are removed from the hat. Continue until enough Reserves have been chosen.
If enough Reserves cannot be chosen, then randomly add Things from the Base Set until there are enough.
You can choose your sets using the Pick button in the Practice and Friendly game set-up screens.
