It's impossible to miss the big orange button with a currency value in the screen's lower-left corner. That's where you want to go once the Sevens & Books slot loads. Use the button to adjust the size of your total bet/bet per line. Every player can play with as little as €0.05 and as much as €100. There's a blinking green button in the lower-right corner. Use it after selecting the right bet.
Everything on the screen of this game is straightforward. You have a purple Max Bet button that players can use when they want to place a maximum bet. The green Auto button is for those who prefer automated spins. In the upper-left corner, there are a few other buttons. Here, you can control the sound effects or get access to the payout table.
The Sevens & Books slot stands out from the crowd when it comes to the number of basic symbols in classic slots. The list of basic symbols has nine retro icons. First and foremost, there's a cherry symbol. Hit three of them on a payline to win 5 times your bet. The same prizes are reserved for players that will land three lemons, plums, or oranges.
The value of the symbols goes up with the symbol of the grapes. Three of them on any active payline will deliver 10 times your bet. If you have the luck to hit three watermelons on a line, you'll get 15 times the bet. With the help of three green bar icons, players will receive a prize worth 20 times their bet. 25 times the total bet is given to players that will land three bells on a single payline. The most valuable basic symbol is the lucky red seven. You should expect 50 times your total bet if you manage to get three sevens on a payline.
The only special symbol is a paying symbol too, but it will only return your bet if you have three of them on any position on the matrix.
It's not difficult to choose the best Sevens & Books bonus feature when there's just one of them here. It can be triggered with the help of the scatter icon that comes in the form of a book. When you land three books anywhere on the screen, you will activate a round of 10 Sevens & Books free spins.
It is possible to activate more free spins during this mode. You will need more scatters for that. Before the round begins, one of the basic symbols will be turned into a bonus symbol randomly. If you make a winning combination, and there's a bonus icon on the matrix, the reels with bonus icons will be covered with these icons. So, after you get paid, you will get another chance to win with bonus symbols evaluated as scatters in situations like this.
There are no other bonus features in this game except for the classic gamble feature. Players can choose to gamble their last winning through a card game or a ladder game. Both of them are games of luck that can help you multiply the winning by two. However, if you fail, you will lose the last winning.
Players should expect a Return to Player percentage that is just a little bit above the average. We are talking about Sevens & Books RTP of 96.10%. This is a medium-level volatility game.
