Gonzo's Quest features five columns and three rows but, because of the way the game plays, we're not sure you could call them reels exactly. Like in the mobile games Bejeweled and Candy Crush, a winning line will dissolve and bring the symbols above them tumbling down.
This also triggers a multiplier of 2x, with successive multipliers of 3x and 5x also possible if more wins are triggered, which is applied to any winning lines that are formed when the symbols above come tumbling down.
NetEnt call this function Avalanche and, although there's no way to use skill to manipulate the outcomes of it, it's still a nice break from the norm and can be a useful way to score some extra wins.
There's also a Free Fall bonus feature, which is equivalent to free spins, but a multiplier is again in play here and all multipliers that kick in as a result of an Avalanche are much improved. It's in this bonus round that players are most likely to win big, so it's difficult to stop a smile from spreading across your face when it comes around.
