Play Halloween Adventure for Free

As the moon shines its dim light in the middle of a dark forest, the spine-tingling events of a sinister night beckon in the incredibly designed Halloween Adventure online slot. The dark blue grid is set against the background of a dimly moonlit jungle where frightening giant tree shadows are visible. The instrumental and sound effects are scary enough in a way that perfectly complements the theme and amplifies the spooky vibe.

Gameplay reels are adorned with thematic symbols, while regular symbols are represented by clubs, diamonds, spades, hearts, a potion pot, skulls, purple bats, walking dead, brown spiders, and zombies. As for special icons in the Halloween Adventure slot machine, you’ll encounter the wild and scatter symbols, which are depicted by the witch and a pumpkin king.

The spooky events of the Halloween Adventure online slot unfold on a 5-reel, 3-row grid layout with 30 paylines. A minimum bet of 0.30 is enough to get you started, but for high rollers, the options reach 60 coins per spin. Additionally, this is a high-volatility game, and it has an RTP of 96.00%. Here are your expected returns for matching winning combinations on a payline:

Here are the boosters you’ll tap into as you play Halloween Adventure slot online:

The witch wild symbol can only appear on reels 2, 3, and 4. When the witch appears on the grid, it can help complete winning combinations of any regular symbols on a payline.

As the bonus scatter, the pumpkin can only land on the 1st, 3rd, and 4th reels. The bonus symbols activate the bonus game, which starts with 5 initial free spins. Better still, you can trigger additional free spins during the bonus game and the tombstone selection. The bonus game will end when the zombie hand appears.

The free spins game starts after the bonus game. When a wild witch symbol appears on the grid during free spins, it expands vertically on its reel.

There are two risk mini-games you can pick after you land a paying combo:

Moreover, it is also possible to gamble half your win.

After this scarefest, continue your spirit for adrenaline-packed treasure-hunting adventures by playing other Halloween-themed slots like Inspired Gaming’s The Halloween Golden slot and iSoftBet’s Wizard of Aus slot.
