Def Leppard: Hysteria

Play'n GO licenses another arena act for its rock catalogue with Def Leppard Hysteria, built around the English band's 1987 album of the same name, the record that produced seven hit singles and sold more than 20 million copies worldwide. The slot sets its stage amid smoke and spotlights rather than depicting the band directly, leaving the platform empty as though the group is about to walk on, while a run of the album's tracks plays through the session.

Play'n GO builds the game on a cluster-pay grid, 5 columns by 7 rows, where a win forms from 5 or more matching symbols connected horizontally or vertically anywhere on the board. Low pays are a mix of stars and card suits, worth 0.1 to 0.3 times the bet for a minimum 5-symbol cluster and rising to 20 to 40 times the stake for clusters of 15 or more. Four higher-value symbols sit above them, paying 0.2 to 2 times the bet at the small end and 80 to 1,000 times the stake for a 15-plus cluster. Wild symbols can substitute for any paying symbol regardless of how they land.

Winning clusters are cleared by a cascade mechanic, with symbols dropping into the gaps left behind and any new clusters that form paying out in turn, repeating until a spin produces no further wins. Break It Up can trigger at random on a non-winning spin, shuffling symbols into new positions and placing between 3 and 6 fresh Wilds onto the board. Fire Me Up runs alongside this: each spin nominates one pay symbol, and wins built from that symbol fill a charge meter, taking four qualifying wins to complete it. Once full, and once cascades on that spin have finished, the grid gains another 3 to 6 Wilds of its own and the meter resets for the next cycle.

Free spins are reached through Pour Some Sugar On Me, where a win landing on a specific position lights up a letter; spelling out SUGAR across those positions awards 5 free spins. The charge meter carries over into the round, filled the same way as the base game, but completing it here drops a multiplier Wild instead of adding plain Wilds. That Wild falls one row with each cascade, destroying any symbols beneath it and gaining +1 to its multiplier at every step until it tops out at x7; when a winning cluster contains two or more of these multiplier Wilds together, only the biggest of them is counted. A separate feature, Sugar Me Sweet, can trigger on a non-winning spin during the round, converting 6 to 9 randomly chosen symbols into whichever symbol the charge meter currently has selected.

Play'n GO rates Def Leppard Hysteria at medium volatility, 6 out of 10, with a default return to player of 96.27% and four lower configurations available down to 84.28% depending on where it's deployed; hit frequency isn't published. The maximum win is 10,000 times the stake, and betting runs from 0.10 to 100 per spin. Released in March 2022, the game leans on its cascading multiplier Wilds during free spins as the main route to its top payouts, with the charge-meter mechanic doing double duty in both the base game and the bonus round.
