The Book of Osiris video slot is configured on five columns in four rows and has 25 paylines. Paylines are fixed, which means that you play all 25 all the time. Symbol combinations need to be arranged from left to right in columns, starting from the first column on the left. The rule of one win per payline also applies here, and winnings on multiple paylines are possible at the same time.

The symbols of this slot can be divided into two groups. The first group consists of regular symbols, including the Egyptian cross, a snake and a cat, and the second group includes special symbols. These are symbols that have special functions or serve to launch a bonus game. The first special symbol is a wild with the image of Osiris. This is a symbol that replaces all regular slot symbols and participates in building winning combinations with them.

The book turns other symbols into wilds!

The symbol of the book, after which many slots were created, is another special symbol. Each time a book appears on the game board, it will convert one symbol to another slot symbol. All copies of this symbol on the board will, together with the first one, turn into wilds! If more than one book symbol lands at the same time, more symbols will be converted into wilds. The conclusion is self-evident – turning symbols into wilds leads to more simultaneous winnings!
