Symbols and payouts

The combos of regular symbols you will make in the Book of 99 video slot will determine the size of the prizes. There is a list of nine regular symbols in this online slot. In this case, the standard playing card icons are decorated with various gems. The 10, Jack, and Queen icons have blue, green, and purple gems, respectively. Three, four, or five identical symbols like that will provide 0.5x, 2.5x, or 10x the bet. Users that will land three, four, or five Kings or Aces (with orange and red gems) will win 0.5, 4, or 15 times the total bet.

What’s interesting is that the high-paying regular symbols pay even when you land two matching ones on a single line. Two, three, four, or five monstrous women (Lamia) on a line will deliver 0.5, 3, 10, or 75 times your bet. The Cyclops delivers the same prizes. It’s Penelope that can help you get 0.5, 4, 40, or 200 times the bet as long as you land two, three, four, or five of these icons on a payline. At the end of this paytable, we have Odysseus, a symbol that can bring prizes worth 1, 10, 100, or 500 times your bet.

The Wild Scatter icon is a non-paying symbol.

The Wild Scatter icon might be a non-paying symbol, but it’s the key to the best Book of 99 bonus feature. Logically, it comes in the form of a book with a beautiful cover. It acts as a Wild symbol. This means that it replaces all regular symbols. Simultaneously, this is a Scatter icon, So, if you are lucky to get three or more of these symbols anywhere in view, you will get 10 Book of 99 free spins.

This special round is played on the same reels and lines with the same bet amount. That’s why the payouts you can expect are the same too. But, there’s one different thing. Before the free spins start, one of the regular symbols will be turned into an expanding symbol. So, during this round, it can pay on all ten active paylines according to the number of symbols that will appear on the reels. What’s more, it will pay out on each payline even when the symbols are not connected from left to right.

Whenever a player lands a Wild icon during the base game, the collection bar will go up by one. You will access a round of free spins after you collect 99 Wild icons. Everything in this game is the same except for the bet size. The bet size used in these free spins will match the average of the bet sizes used while you were collecting the Wild icons.
