Who Is the Provider of Medusas Madness?

Medusas Madness is developed by Play’n GO, a well-established provider in the online gaming industry.

How Is Medusas Madness Played?

This slot is played on a 5×5 grid. Symbols drop down onto the grid, and you form winning clusters by connecting four or more matching symbols horizontally or vertically. Only adjacent symbols count towards cluster wins, and there can be no gaps between symbols in a cluster. Clusters can begin anywhere on the grid.

What Happens After a Win?

When you create a winning cluster, the involved symbols are removed from the grid. New symbols then drop into place, and if another win forms, the process continues. This cascading feature keeps going until there are no further wins possible in that round. All winnings—including those from features and bonus rounds—are combined and paid out at the end of the round. Only the highest win per winning combination is paid out, and all wins from simultaneous clusters are added together.

What Are the Betting Options?

You can select your bet using the plus and minus buttons located at the bottom of the game screen. Bets can be set from a minimum of £0.10 up to a maximum of £5 per round. The stake cannot be changed during an active round.

What Special Features Does Medusas Madness Offer?

  • Eye Marks: Eye Marks can randomly appear on the grid. Forming a win on an Eye Mark position opens the eye. When no further wins are possible, two SPECIAL WILDS are added to the grid.
  • Stone Gateway Charge: Winning on symbols charges the Stone Gateway. The following effects occur as the number of winning symbols in a round increases:
    • After 7 symbols: 2 SPECIAL WILDS are added to the grid.
    • After 14 symbols: 2 SPECIAL WILDS are added again.
    • If a win is made with a SPECIAL WILD at this stage, the PETRIFY Stone Gateway Effect is triggered.
    • After 27 symbols: 2 more SPECIAL WILDS are placed on the grid.
    • If a win is made with a SPECIAL WILD, the GAZE Stone Gateway Effect is triggered.
    If multiple charge effects are achieved in quick succession, only the latest effect is awarded.
  • PETRIFY Effect: When triggered, PETRIFY removes a row or column from the grid starting from the winning SPECIAL WILD symbol. Any symbols removed add to the Stone Gateway charge. If PETRIFY removes another SPECIAL WILD, this removal is also initiated from that symbol.
  • GAZE Effect: If GAZE is triggered, one type of regular symbol is randomly selected, and all matching symbols are removed from the grid.

How Does the Other World Free Round Work?

You trigger the OTHER WORLD FREE ROUND after winning on 42 symbols within a round. This awards one free round that includes three randomly chosen Stone Gateway Effects. If you over-charge the Stone Gateway, additional Stone Gateway Effects are added for every three extra winning symbols collected, up to a maximum of seven effects.

During the OTHER WORLD FREE ROUND, Stone Gateway Effects trigger when no further wins are possible.

  • SPECIAL WILDS: Four SPECIAL WILDS are added to the grid.
  • PETRIFY: Four SPECIAL WILDS are added. If a win occurs with any SPECIAL WILD, the PETRIFY effect is activated.
  • GAZE: Four SPECIAL WILDS are added. If a win happens with any SPECIAL WILD, the GAZE effect is triggered.

In this feature, 11 or 12 Eye Marks are visible on the grid. You open each eye by forming a win in its location. Once all eyes have been opened, a MEGA WILD Medusa’s head symbol appears and moves downward with each cascade, disappearing when it reaches the bottom. Cascades continue until no new wins are possible.

What Happens If a Game Is Interrupted?

If a game round is interrupted, all relevant information and placed bets are saved and can be resumed from the point of disruption. If unresolved bets remain undecided after 90 days, they are voided. Any malfunction will void all pays and game rounds.
