Play’n GO

If you have ever claimed a free spins bonus at an online casino, you already know Play’n GO: they are the Swedish studio behind Book of Dead. After nearly thirty years in the business, they are still entirely independent and owned by their founders.

While the rest of the industry was busy copying the Megaways trend, Play’n GO built an empire out of grid slots. They mastered the format with games like Reactoonz on a 7×7 board, Moon Princess and Rise of Olympus on 5×5, and the honeycomb-shaped Honey Rush. The signature of a Play’n GO slot is the charge meter: as you clear winning clusters the meter fills up, so there is always something building on screen. One thing worth knowing before you play for real money. Every Play’n GO game ships to casinos with adjustable return settings, from around 96% down to 84%, and the casino picks which version you get.
