The higher-value symbol is the tiger, and Lara is a familiar pose and complex puzzle. You will then be taken to a screen showing multiple idols, you can choose three, four or five depending on the number of symbols you originally logged in. Each idol is worth the cash amount and then you will return to the main game.
The special symbol is an idol that can trigger Tomb Bonus, with a gun (scatter) and a tomb Raider wild symbol.
