BetSoft’s 2022 Book programme middle pillar<\/a>, runs 95.58% RTP on high volatility with a 35.03% hit rate, and offers a 20,168x max win ceiling \u2014 roughly \u20ac363,024 at a \u20ac18 spin. The free demo runs widely on BetSoft-licensed operators.<\/p>\nHow BetSoft Book of Helios Works<\/h2>\n
The reels span a 5-reel \u00d7 3-row grid with 10 fixed paylines \u2014 compact by modern standards but enough surface for the Greek-myth symbol set. Helios, Olivia Brave, the Book of Helios, magical artefacts, and stylised card royals fill the paytable.<\/p>\n
Coin sizing runs $0.10 to $10 per spin \u2014 a tighter range than BetSoft’s older Slots3 titles. The Greek-myth art direction uses a golden palette with the temple of Helios as backdrop, and Helios himself drives his magical fiery chariot across the sky between spins.<\/p>\n
The 35.03% hit rate places Book of Helios above BetSoft’s slot average. Roughly one in three spins lands a paying combination, propped up by the multi-role Book and expanding-symbol mechanic during Free Spins.<\/p>\n
The Book of Helios Symbol \u2014 Wild & Scatter<\/h2>\n
The Book itself plays a dual role: WILD substituting for any symbol on the reels, and SCATTER triggering the Free Spins round when three or more land anywhere on the grid.<\/p>\n
We see that multi-role design carry forward the template BetSoft established with Book of Darkness in 2020 \u2014 a Wild-and-Scatter Book symbol where every Book landing gives us dual utility. The compound effect lifts base-game hit rate without inflating the bonus-trigger probability beyond standard.<\/p>\n
Free Spins, Expanding Wilds & Compound Multipliers<\/h2>\n
Three or more Books trigger the 10-spin Free Spins round. The mechanic opens with theatre: Helios charges in on his chariot and expands one random symbol to fill its entire reel before the first spin lands.<\/p>\n
During the round, every Book of Helios wild or scatter symbol that lands also expands to fill its reel. Each expanded symbol carries a multiplier between 1x and 5x, and expanded Wilds multiply each other when they share a winning combination.<\/p>\n
