What it is
A beer-garden slot from Hacksaw on 5 reels and 4 rows that pays in ways. Stackways symbols fill a reel with copies of one symbol, and the revealing kind can stretch the reel to 10 symbols tall. A stack only happens when it would make a win.
The bonus
Book of Stackways gives 10 free spins and picks two symbols as specials. When a special lands on three or more reels, it stacks up those reels, book-slot style. Four bonus symbols at once upgrade it to the Super Book of Stackways, which picks four special symbols instead of two.
In Haddzy's hunts
Opened once in Haddzy's hunts, on 16 Aug 2026. Only one bonus in the record so far, and it landed small. One bonus says little either way.
Who it suits
Book slot fans who want a lighter, funnier take on the idea.
Good
- A book bonus with a twist
