Description of the slot machine

I would recommend at least once to play in Spectrum slot machine. This game will bring you into the world of nostalgia. The classic characters with neon signs will remind you of the past. But innovative gadgets give the game originality and profitability. I was pleased with the presence of 243 ways of forming the winning combinations and the bonus option of Reel Locking.


  • Number of reels – 5
  • Number of pay lines – 243
  • The size range of bets – from 0.25 to 50.00
  • Maximum winning for a spin – 2 000 (at a game at the maximum stake from 5 symbols of Triangle with colour lasers)
  • Wild symbol – yes (an inscription in the circle)
  • Bonus game – yes
  • Special option — yes (Reel Locking function)
  • The expected payout percentage (RTP) of Spectrum slot is 96,61%


The bonus feature is called Reel Locking and is activated before each spin. The slot can choose two reels, which will operate synchronously. The symbols on them will be the same. It is worth noticing that these reels can join another reel. The Wild in this feature will replace all symbols but can be only on all the reels except the first reel.
On this slot, there is also a standard risk game.
