Happy Halloween is a video slot game whose theme reflects the spooky autumn holiday celebrated in many countries throughout the world. The game features 5 reels frequented by ghouls, mummies and monstrously delicious treats! Up to 50 lines can be activated, with a bet of up to 5 coins of a chosen denomination per line. Lines are numbered and always activated in numerical order (1, 2, 3, etc.).

The game includes a wild symbol (the jack o’ lantern), which appears on reels 2-5. This wild symbol can help to comprise winning combinations by substituting for any other reel symbol except the scatter symbol (the witch).

Three scattered witch symbols that appear anywhere on reels 1-3 result in a prize of four times the total bet plus a sequence of 10 free spins. On each free spin, two new wild symbols are added to reels 2-5. Newly added wild symbols are stacked onto existing wild symbols to elongate the stack of wilds on each reel and boost the odds of creating winning combinations. 10 additional free spins can be triggered during any free spin to give the player the chance to win a total of 20 consecutive free spins with ever-growing stacks of wild symbols for a total possible win of 1,000,000 coins!

The high-paying symbol that depicts the lantern-wielding ghost always appears in a four-symbol high stack in the main game as well as on free spins. When free spins are triggered, an additional high-paying symbol is chosen at random to appear in stacks of four throughout the sequence.

The game also features an optional Gamble round that provides an opportunity to multiply the total prize on any spin in the main game by correctly guessing the colour or suit of a hidden card. The Gamble round can be played up to five times in a row for a total prize of up to 2500 coins.

With its many surprising treats, this slot reflects the true spirit of Halloween!

The RTP is 96.50%.
