Game Rules

  • All symbols pay in blocks of a minimum of 5 symbols connected horizontally or vertically.
  • The game is played on a 7×7 grid of symbols.
  • All symbols pay according to the quantity in a block. The paytable lists the values for 5 up to 49 symbols of each type in a single block.
  • Only the SCATTER symbol can appear on all reels without restrictions.

Tumble Feature

  • After every spin, all winning symbol combinations are paid and then removed from the grid, except for SCATTER symbols.
  • Remaining symbols fall to the bottom, and new symbols drop into the empty spaces from above.
  • Tumbling continues until there are no more winning combinations.
  • All wins from the base spin and resulting tumbles are added to the player’s balance after the sequence is complete.

Fire Portal Wild Feature

  • The FIRE PORTAL WILD symbol substitutes for all symbols except SCATTER.
  • It appears as a result of a winning combination that does not already contain an instance of itself.
  • It appears in a random position within the area of the winning combination after those symbols are removed.
  • Each time a WILD is used in a winning combination, its multiplier increases by x1, and it moves to a random adjacent position within the combination area.
  • The multiplier applies to the win of all combinations that contain the WILD.
  • Two or more WILDs in a winning combination merge, and their multipliers multiply.
  • If shared by multiple winning combinations, WILDs merge with priority given to the combination with the most WILDs, then to the highest-paying symbol.
  • WILDs remain on the screen until all tumbles resulting from a spin are complete.
  • The multiplier can reach a maximum possible value of x2500.

Free Spins

  • 3, 4, 5, 6, or 7 SCATTER symbols trigger the Free Spins feature, awarding 10, 12, 14, 16, or 18 free spins, respectively.
  • During Free Spins, FIRE PORTAL WILD symbols remain on the screen until the end of the round.
  • If WILDs are present when Free Spins are triggered, they remain in the same position throughout the round.
  • Additional 3, 4, 5, 6, or 7 SCATTER symbols retrigger the Free Spins feature, awarding extra 10, 12, 14, 16, or 18 free spins respectively.
  • Special reels are used during Free Spins.

Max Win

  • The maximum possible win amount is limited to 10,000 times the bet. If reached, the round ends immediately, and any remaining features are forfeited.

Ante Bet

  • The player can increase the bet multiplier to 30 times per line with the Ante Bet option.
  • Activating the Ante Bet increases the chance to hit BONUS symbols.

Volatility and RTP

  • This is a high-volatility game, meaning payouts occur less often, but the potential for large wins in a short amount of time is greater.
  • Only the highest win per combination is paid. All wins from multiple blocks in a single spin are added to the total win.
  • All win values use the base bet as a multiplier.
