Most slots put the reels inside a box. Monster Tunnel on Sky777 throws the box away. The grid has no frame, so the symbols sit straight on the artwork, and the whole screen feels more like a wall of street art than a machine.
The Monster Tunnel look
The frameless design is the first thing you notice, and it does make the game feel newer than a lot of the Sky777 catalogue. The tunnel setting leans on graffiti: tags, spray paint and the sort of art you'd walk past in an underpass.


The graffiti symbol and free games
Despite the name, the icon that matters is not a monster. It is a piece of graffiti art, the work of a struggling street artist that few people would ever stumble across. Here, it is what sets off the free games.
The number of free games depends on how many of those symbols you find:
- Three symbols: at least 5 free games
- Five symbols: 15 free games
Four symbols sit in between; check the paytable in the game for the exact count.


Staking on Monster Tunnel
Free games are where most slots save their bigger results, and three symbols is the realistic target. Five is rare. Choose a stake you can repeat for a long run of spins, because the feature can take a while to arrive. If it hasn't shown up by the time you've used your planned budget, stop there rather than chasing it.
