Book of Dead
Day 22 was Book of Dead by Play’n GO, the 2016 classic, and the question was whether it’s still relevant. 10 bonuses, a best win of 114x, two 100x base game wins and a profit session. Still a yes.

Day 22 - Book of Dead - Slot Review
On day 22, I went back to a classic with Book of Dead by Play’n GO, released in 2016. This test isn’t about proving whether the game is good, because it was the number one slot for a long time. What I wanted to find out is whether it’s still relevant today, when new releases come with huge max wins and cluster mechanics everywhere.
It’s a 5x3 grid game with 10 paylines and a 5,000x max multiplier potential.
The game revolves around one feature, the Expanding Symbol. Land 3 Scatter symbols and you unlock 10 Free Spins. Before the free spins start, an ordinary symbol is randomly picked as the Special Expanding Symbol for the whole round. After the regular wins are counted, that symbol can expand to cover its entire reel, but only when it creates additional wins on active paylines, and the symbols don’t need to be next to each other to count. Land 3 or more Scatters again during the free spins and you get another 10 free spins.
What you’re chasing is a free spin round where Rich Wilde is the expanding symbol and the screen fills with him. It’s the dream scenario of this game, and also the reason the bonus can pay so well or die so quietly.
I didn’t get a full screen in any of my bonus rounds, but I triggered the bonus 10 times in total. My best bonus paid 114x. The session itself was two different stories. For the first 500 spins nothing happened, and this game asks for patience. In the last 500 spins it started to rain bonuses and base game wins, including two base game wins of 100x. Because the bonus frequency was so generous, I closed the session in profit even without a screen-filling monster.
So is Book of Dead still relevant? Yes. The mechanic is simple enough to understand in one spin, there are no layers of multipliers or cluster math to learn, and it still delivers the tension of watching a bonus symbol decide whether a round is nothing or something. The fact that it holds up against modern releases after all these years says a lot on its own.
1000 Spins Approved? Still a Yes!
