Viking Madness by Caleta Gaming is a five-reel slot with 30 paylines, a high-volatility structure, and an RTP listed at 96%. The game uses a Norse theme with Viking character symbols, axes, helmets, coins, and a Wild symbol that substitutes for other icons. Bet levels range from 0.3 to 180.
The bonus system is built around the Thunder Quest Bonus, which is triggered by 3 or more Bonus symbols on reels 2, 3, and 4. Players then choose one of three chests to enter a bonus path: The Big Catch, Sticky Wilds, or Free Spins. Free Spins begin with 10 rounds and apply a 2x win multiplier, while the Sticky Wilds feature awards 5 Free Spins and keeps Wilds fixed in place for the duration of the round.
This demo version lets players play for free and review the rules before deciding whether to practice before playing for real money. The layout keeps balance, bet, lines, and win information visible alongside the main grid and bonus panels.
