In their forbidding stone chamber lit with weird ultraviolet light, a witch and warlock practise their occult charms in the RTG slot game Warlock’s Spell. Apart from throwing magic spells of matching symbols to win prizes and mixing potions to determine bonuses, it has little storyline, but a pervasive air of mystic sorcery.

Warlock’s Spell features five reels and 20 paylines. RTG provides fairly basic animations after wins and before the bonus game, and an unimaginative slots soundtrack, but the 3D symbols are painted in attractive multi-coloured detail, and game play proceeds quite quickly in Auto Play mode. Players can bet from 1 to 500 credits per payline.

Ten Ordinary Symbols in Base Play

The six poker-hand low-value symbols in Warlock’s Spell, the 9, 10, J, Q, K and A, are created in a font with touches of both ancient Greece and Celtic runes, glowing in various colours in a field of stars to enhance the mystique. Paired as 9 and 10, J and Q, and K and A, each pair wins equal-value prizes for three, four or five matches in succession from Reel 1 on the same payline. The K and A win 10, 30 or 250 credits for each of the three possible combos.

Warlock’s Spell’s high-value themed icons win prizes for two or more matches on a payline, and the coruscating crystal ball and bilious green potion bowl are also paired in value. The win 3, 30, 250 or 500 credits for two, three, four or five matches. For the same sequences, the gold occult talisman wins 5, 100, 500 or 1,000 credits, and the spooky black cat wins 10, 100, 1,000 or 5,000 credits.

Two Wilds and a Variable Bonus

The witch appears on Reels 1, 2 or 3 and the warlock appears only on Reels 3, 4 or 5, but both function as Wilds in Warlock’s Spell. Not only can they substitute for any ordinary symbol to complete a winning combo, but players also win individual prizes for mixed runs of Wilds on a single payline. For one, two, three, four or five mixed Wilds from Reel 1, the prizes are 2, 20, 200, 2,500 or 10,000 credits.

A spell book serves as the Warlock’s Spell Scatter: for three, four or five appearances in any position, they win prizes of 2X, 20X or 100X the total spin bet. Three or more Scatters also trigger the bonus round, which begins with the Potion Prize Feature. The player is faced with a potion they must complete. Picking the correct ingredient triggers the free spins game immediately at the top level, but each time the player chooses an incorrect ingredient, the number of free spins in the bonus round decreases. Players can thus get between 100 and 8 free games.

Familiar RTG Random Progressive Jackpot

A feature that will be familiar to fans of RTG slots is the progressive jackpot, which appears on the meter above the Warlock’s Spell reels. Depending on intervals between wins, this jackpot can be worth thousands, or tens of thousands of dollars.

However, there is no combination of symbols in Warlock’s Spell to trigger it; it is activated entirely randomly. So when playing Warlock’s Spell, the player could be awarded the progressive jackpot after any spin.

Like blackjack in Canada is offered at Microgaming casinos on desktop or phone, this slot is available at online or mobile RTG casinos.
