Winterberries series
Few fruit-slot revivals occupy the frozen-nature niche as precisely as Yggdrasil Gaming's Winterberries series, which keeps berries on a 5x3, 20-payline screen while pushing the sequel toward sharper bonus risk. Released in 2014, Winterberries pairs its high-volatility profile with free spins, respins and multipliers. Its 96.7% RTP and 2,500x maximum make the original the more restrained version despite that volatility label.

Winterberries 2 retains the same reel and payline structure in 2023, but adds wilds, scatters, extra free spins, a bonus buy, a bonus bet, changing reel sets and respins that lock wins. The maximum rises to 10,000x as RTP falls to 94%. Rather than adopting a variable-ways engine, the sequel modernizes the fixed-line format through stronger feature access and a fourfold increase in its payout ceiling.
