Hell Mania — RTP, volatility and max win

A devil, blood, hearts and hellfire on a black and red backdrop make Hell Mania by SYNOT a horror slot. Wins can grow through symbols that stretch across their reel, and any win can be pushed into a double-or-nothing gamble.

The palette stays tight: black, red and flames, with a devil's face, blood and a heart as the recurring imagery. The grid is 5×3 with just 5 paylines, a lean line set that recalls classic fruit machines. Every spin costs between €0.20 and €100. SYNOT released Hell Mania on May 1, 2017. The hit frequency of 11.42% stands out: with so few lines, most spins end without a win.

There are 5 paylines, fixed across the 5×3 grid. A payout comes when identical symbols meet in a row on one of them. With so few lines, a lot rides on the expanding symbols: once a symbol fills its whole reel, it covers every line on that reel at once. The wild fills in for a missing symbol on a line.

Expanding symbols: a winning symbol can stretch over its entire reel and so serve several of the few lines at the same time.

Multiplier: wins can be boosted by a factor, which on such a small line set is the main route to bigger payouts.

Gamble: after a win, Hell Mania offers a double-or-nothing round. Taking it puts the amount just won at stake, to be doubled or lost.

With so few lines, the symbols that stretch across whole reels carry much of the winning in Hell Mania, and other games built on that mechanic are grouped under inferno slots with expanding symbols.
