Mystery Box Demo – Play for Free

The Mystery Box online slot can be found on the provider’s platform with no strings attached. At first glance, it looks straightforward and easy to play, but experienced players know that there’s much more beneath the surface. Use the demo version to test the payout ratio and some potentially profitable betting strategies.

If you want to bet real money, check our recommended Mystery Box casino sites. Each one provides exciting opportunities to both beginners and seasoned players. Operators like Jackpot Joy are properly licenced and regulated. In addition, you can find tempting bonus offers and VIP promotions.

Mystery Box Reels, Paylines & Theme

The Mystery Box slot machine deviates slightly from the provider’s typical line of work. Golden Hero is known for its passion for the classic 3-reel spinning machines. However, this game comes with a 4×4 playing grid, no active paylines, and can’t be actually called a spinner.

The sixteen tiles rotate to reveal mysterious symbols, which can bring lucrative rewards. To collect payouts, punters must find 3 or more identical characters. They can be anywhere on the gameboard, and the Cluster Pay rule doesn’t apply in Mystery Box. Graphically and functionally, the machine performs great! The gameplay is smooth and fast.

If you want to activate the Turbo Mode, just hold the Spin button. In addition, You will find an Autoplay tool, advanced settings, and a nicely developed bet modifier. There are no progressive jackpots or free spins included by Golden Hero, but a special Mystery Bonus round. If you are eager to learn more, continue with our Mystery Box slot review!

Mystery Box RTP, Symbols & Payouts

The Mystery Box RTP rate is 96.43%. The volatility levels can be determined as a medium to high, which means extra caution with the bet size! You can find 12 primary symbols on the grid and one special one – the Mystery Chest. Basic figures pay for 3 to 16 identicals on the gameboard.

The Pink Crystal and Ceremonial Glass are the highest paying symbols with potential rewards from 0.75x to 1,000x the bet. Book and Parchment pay x0.50 to x850, Crystal Ball, Hourglass, Keys, and Candles – x0.40 to x750, and Compass, Potion, Pouch, and Inkwell – x0.25 to x700!

Advantages:
  • Respin Feature
  • Mobile-Friendly

  • Bonus Multipliers
  • Autoplay Functionality
Disadvantages:
  • No Free Spins
  • No Progressive Jackpot

The Mystery Box slot provides 16 betting levels, starting from 20p and ending at £100. At first glance, it might look insufficient for some high-rollers, but the top wager combined with the maximum win of x7,270 creates a truly incredible opportunity. Progressive jackpots are unavailable in this outstanding game!

Unlock Fantastic Mystery Multipliers

Whenever a winning combination is present on the grid, a free Respin initiates. Players can collect additional profits by matching new characters or upgrading the already existing formation. During a respin, all identicals and Mystery Chests remain still, while the other tiles rotate again.

Payouts related to the same symbol combinations are summed up. Thus, you can collect up to 16 increasing rewards. If at least 5 Mystery Chests are in view at the end of the round, the Mystery Bonus activates. Pick one of the 4 chests and reveal a multiplier of x10 to x1,000!

Mystery Box Mobile

The Mystery Box slot machine performs brilliantly on mobile devices. Although a dedicated application is currently missing, players can enjoy the game on iOS, Windows, and Android phones and tablets. The visual appearance is similar to the desktop one, with some minor displacements of the control tools.

Mystery Box Reviewer Opinion

As a fan of the classic casino play, I personally appreciate the qualities of the Mystery Box online slot. The excellent RTP rate and regular payouts fit perfectly in my betting strategy. However, you don’t have to forget that they are only theoretical. Here you can read more about the meaning of the RTP coefficient and find more impressive titles.

On the other hand, hitting larger rewards is rare, in my experience. During the test game, I managed to reach x5 combinations only and didn’t have the chance to activate the Mystery Bonus. In any way, the slot is engaging and possesses massive winning potential.
