Expert Review

The gameplay will not bring any surprises. The most valuable symbol of the video slot is a book. This icon is a universal substitute (Wild), is paid regardless of the lines, like Scatter, and activates 10 free spins.

Briefly about the features of building combinations in free spins:

• One of the line symbols is assigned expanding. When dropped, it will fill the entire reel.
• Combinations are paid with breaks.
• Winning chains do not have to start on reel #1.

These are traits common to all slots with "Book of" mechanics.

The table gives an understanding of the overall picture of the test.

Line payouts are very weak. So, for the five rarest and most valuable symbols, the player will receive only 20 total bets.

Without the bonus game, the loss will increase. The worst interval during the test is the loss of -350 bets per 500 spins.

Three book special symbols activate the bonus. Such an event occurs approximately once every 140 rounds. The bonus game triggers 10 free spins. The free spins are more generous than in the classic Book of Ra slot gameplay. There are two features:

• The dropped Wild (book) also expands and fills the entire vertical.
• In half of the cases, the wild has a multiplier for combinations — from x2 to x5.

К сожалению, фриспины без перезапуска и без продления.

The way to win x100 bonus and more in total stakes is to select one of the most expensive symbols as an expanding element. Assignment occurs automatically, randomly, without the participation of the player.

Особенности автомата

The main difference between the gameplay of this slot and the classic Book of gameplay is the additional Wild features in free spins. The special symbol expands (fills the entire vertical) and has multipliers for the combinations in which it participates.

Other features of the device:

• Dynamic paytable. When you increase or decrease the bet, the value of the win on the line immediately changes.
• The limit on automatic spins is no more than 100.
• The slow rate of autoplay is about 25 spins per minute.

Слот определенно для лоуроллеров. Предлагаемый диапазон ставок — от 6₽ до 250₽.

Expert tips

The test showed unevenness of any events in the Book of Helios slot from Betsoft. The bonus game was triggered three times in 50 spins. On the other hand, there were two periods without free spins lasting over 250 rounds. The spread of winnings in the bonus is also significant: from 10 to 120 bets.

1000 spins is a very small distance to understand the nature and potential of the slot. Before playing for real money, a longer test in demo mode is recommended.

The Book of Helios video slot is not suitable for beginners. Waiting for a bonus game can hardly be called a pleasure when the balance is rapidly declining.

The machine is available in any online casino where the Betsoft provider is represented. This is 90% of the total number of gambling sites. It is unlikely that the Book of Helios will be banned for wagering casino bonuses, but the high volatility machine is not suitable for this purpose.
