Holy Hand Grenade — RTP, volatility and max win

A grey medieval castle haunted by the devil is where Print Studios sets Holy Hand Grenade. The game collects energy symbols, swaps symbols on the grid and leads via scatters into free spins with multipliers.

Holy Hand Grenade came out on March 30, 2023. One row taller than the classic reel layout, its 5×4 field carries 26 paylines. The stake per spin moves from €0.10 to €90. An optional bonus bet can be switched on, and the game also sells direct entry to the free spins.

Holy Hand Grenade pays on 26 paylines across its 5×4 grid. Lines pay when equal symbols follow one another from the first reel. There is no wild; instead, the symbol swap exchanges certain symbols on the grid for others.

In the base game Holy Hand Grenade collects energy symbols. That collection builds up over the spins and powers the game's features, while the symbol swap exchanges symbols on the grid.

Scatter hits send you to the free spins, where multipliers boost wins and extra free spins extend the round. The game also switches reel sets, which changes what the reels carry. A buy option skips the wait; the optional bonus bet, by contrast, raises the stake per spin.

Holy Hand Grenade lets you switch on a bonus bet that raises the stake per spin; other Inferno titles with the same option are listed under inferno slots with a bonus bet.

RTP 96.45%, higher than 85% of the 400 Inferno slots. Background: how RTP works on a slot. Volatility High, like 85 of the 180 slots in the Hell & devil theme. Background: what slot volatility means. Max win 20,000× (€1,800,000 at the highest stake). Background: what max win means on a slot.

At 20,000×, the cap tops 92% of the Inferno slots, one of the highest ceilings in the catalogue. Its return of 96.45% is strong too.

High volatility follows from the design: nearly all of the path to the biggest win runs through free spins with multipliers and extended rounds.

Holy Hand Grenade is offered at more than one return level; how far those levels sit apart, and which Inferno slots also come in tiers, is set out on the RTP of inferno slots page.

Its ceiling puts Holy Hand Grenade among the games with the highest win potential, and the max win comparison shows which Inferno titles go even further.
