How to Win at Boss Level

The playing card royals are the lower payers, as they are in so many slots, and can reward you with up to 1x for five. There are also briefcases and a whisky and cigar symbol, offering between 1.25x and 2.5x for five-of-a-kind.
Boss Level Bonuses
Let’s take a look at the Boss Level bonus features you could unlock if you choose to play this game:
Powerblock Safes
The Powerblock safe symbols appear above the central three reels and can move on to the grid when you land Powerblock Activation symbols.
Powerblock Prowess
Landing one of the Powerblock Activation icons on the central three reels will cause the safe above to move on to that reel. Any wins that connect with the safe will unlock a security level, and one of the green safe lights will go off for each connecting win.
Unlock the safe to reveal your multiplier. The options range from 2x to an impressive 100x.
Unlock Powerblocks
Each Powerblock has a different level of security and needs different numbers of wins to unlock. The bronze needs one connecting win, the silver needs two and the gold needs three to open.
Locked Powerblocks remain on the grid and move down a row with each spin. They will then either create a winning combination or drop from the grid, allowing a new one to land on the top of the reel.
Wild Symbols
These cannot replace the bonus scatter symbol and don't appear on the first reel.
Free Spins
The bonus scatter symbol triggers the free spins bonus if at least three land. You get eight free spins for three scatters, ten for four and twelve for five.
Each win during the free spins bonus will add an extra row, and these don’t reset between spins. The increases only stop when you reach 10 rows. Keycards and Powerblocks can land and bonus scatters add an extra free spin.
Cascades
All wins trigger a cascade, and a new row is added with each consecutive symbol drop.
Keycards
These add extra rows without needing a win. You get one more row if a green keycard lands, two rows for a blue keycard and three for red. You can land more than one keycard in a spin.
Win Modifiers
As many as three modifiers can activate on any base game spin. These are:
- Mega symbols whereby a random symbol is transformed to become a 2x2, 3x3 or 4x4 icon.
- Max Ways can cause the reels to spin you in the maximum winning ways for a single spin.
- Powerblock Add where between one and three Powerblocks will appear on the grid.
Boss Level
Experience increased payout potential by playing on a 5x10 grid with 100,000 ways to win.
