- All symbols have a stricken version showing the word DOUBLE. Any winning combination is doubled when 1 of 3 matching symbols is stricken.
- A second stricken symbol on a winning combination redoubles (x4), and a third redoubles again (x8).
- Look for the 7 symbol decorated with Poseidon’s trident. Match 3 of them for a high pay. Match 3 of the stricken version of that symbol to unlock the highest possible pay.
