MADICLUBBook of Helios, one of the dice titles at Madison Casino, the licensed online casino, is the dice edition of the BetSoft favourite. The game brings an ancient sun-soaked theme to the dice slot format with a high-volatility profile and clear win potential. It combines 10 paylines, a 95.58% RTP and a top win of 20,168x, so each round can feel measured at lower stakes or more ambitious when you raise your bet.
Set your preferred bet from EUR 0.2 to EUR 20.0 before starting a round. Because this is a dice slot, the play style blends slot-style outcomes with a dice-led presentation, while wins are still evaluated across 10 paylines. Keep an eye on the feature symbols, since Wilds can strengthen combinations and Scatter-led bonuses can open Free Spins with added multiplier and expanding potential.
Wins land across 10 paylines when matching symbols line up on active winning patterns. The game carries high volatility, so results tend to swing more sharply and bigger payouts appear less often, balanced by a top win of 20,168x. Wild symbols help complete combinations, while Scatter symbols and feature triggers add extra routes to stronger returns through Free Spins, multipliers and expanding action.
Book of Helios is built around its paying symbols and a set of bonus mechanics that drive its biggest wins. Here is how each feature works.
A Wild substitutes for regular paying symbols to help complete winning combinations on the 10 paylines. That gives each spin a stronger chance of forming a line when one symbol is missing. In practical play, Wilds add flexibility to the layout and can turn near-misses into landed wins.
A Scatter pays independently of paylines, so its value comes from appearing anywhere in view rather than landing on a fixed line. It also acts as a bonus trigger, giving you another way to reach feature play beyond standard line wins. That makes Scatters important both for direct payouts and for unlocking extra action.
Free Spins award a sequence of spins that do not deduct from your balance. This feature gives you extra chances to collect wins while staying in the game for longer on the same triggering result. When Free Spins combine with other bonus elements such as multipliers or expanding symbols, payout potential can build more quickly.
A Multiplier increases the value of a win by multiplying the payout that lands with it. Instead of only paying the base amount, a successful combination can be boosted to a larger return in a single result. This feature adds punch to both regular wins and bonus-round outcomes, especially in a high-volatility game.
An Expanding feature enlarges a symbol so it covers extra positions, which helps complete more winning combinations at once. When a symbol stretches across additional spaces, it becomes easier to connect matching symbols on multiple paylines. That can create broader coverage on the layout and lift the value of a favourable spin.
The presentation leans into a radiant ancient theme, suggested by the Helios name, with a bright, mythic atmosphere that suits the game’s higher-risk profile. As a dice slot, it stands apart from a standard slot in feel while still keeping the familiar structure of paylines, feature symbols and bonus-trigger moments. The result is a style that feels both distinctive and easy to follow.
The demo version lets you explore the dice slot format, theme and feature set without placing a real-money bet. It is a practical way to test how the high-volatility rhythm feels, see how Wilds and Scatters shape play, and decide which stake level suits you before moving to real funds.
