Northern Temple Bonus Buy Slot by Evoplay

For 54x the total bet, the buy option drops you straight into 15 free spins where the win multiplier never resets. That persistent multiplier is the reason this variant exists alongside the base Northern Temple - buying in means skipping the base game grind and landing directly in the mode where cascades compound on each other.

The grid grows during play. Every winning tumble clears matched symbols and adds a row, stretching the reels from three rows up to six. At full height, 7,776 ways replace the starting 243. Each tumble also pushes the win multiplier up by one with no cap. In the base game that multiplier resets every spin, but free spins carry it forward - so a chain of six or seven tumbles on spin 2 means spin 3 already starts at x7 or x8, and it only goes up from there.

Coin symbols are the second payout system layered on top. They stick to the reels through an entire cascade sequence, and once tumbles stop, any group of three or more Coins cashes out. Each Coin reveals a hidden bet multiplier, and those values get scaled by whatever the win multiplier reached during that chain. Coins landing early in a sequence just sit and wait; Coins still on the grid after a long chain benefit from the inflated multiplier when they finally resolve.

Frost-blue stone columns border the reels against a snowy mountain pass, with aurora-like light streaking across a dark sky. The Norse temple setting uses a muted palette of slate grey, pale gold, and ice blue across the rune-carved symbols. Scatters trigger on reels 2 through 4 only, and landing three during the bonus adds another 15 spins to the count. Wilds fill reels 2-5 and substitute for everything except Scatters and Coins.
