Book of Atlas is a Greek mythology-themed slot game developed by Spinomenal as part of their Demi Gods Series. The game features a 5×3 reel layout with 10 fixed paylines. The symbols on the reels include various Greek-themed icons and books, aligning with the mythological theme of the game.
The game's main feature is the Free Spins bonus round. This is triggered when 3 or more scattered Wild symbols appear anywhere on the reels. Players are awarded 10 free spins, with the possibility of re-triggering additional spins during the feature. Before the free spins begin, players spin a wheel containing all regular symbols (except the Wild/Scatter). The selected symbol becomes the special expanding symbol for the duration of the free spins.
During the free spins, after each spin result is determined, the special expanding symbol will expand to cover entire reels if doing so would result in a win. These expanded symbols pay according to the paytable on all active lines, regardless of whether the symbols are adjacent or not. This mechanic significantly increases the potential for big wins during the bonus round.
The Wild symbol in Book of Atlas plays a crucial dual role:
- As a Wild: It substitutes for all other symbols to help form winning combinations.
- As a Scatter: Three or more Wilds trigger the Free Spins feature and award scatter pays. The scatter pays are as follows:
- 3 Wilds: 2x total bet
- 4 Wilds: 25x total bet
- 5 Wilds: 250x total bet
These scatter wins are paid in addition to any regular payline wins.
The game includes a “Buy Feature” option, allowing players to purchase immediate access to the Free Spins round. The cost of this feature scales with the chosen bet size.
Book of Atlas also offers an Autoplay function and a Turbo Mode for faster gameplay. The Autoplay allows players to set a specific number of automatic spins, while the Turbo Mode shortens the duration of each spin for more rapid play.
