Urartu Slot by Endorphina

Ancient Armenia. Not Egypt, not Greece, not Rome. The kingdom of Urartu controlled the Armenian Highlands for three centuries, built fortress cities around Lake Van, and left cuneiform inscriptions in a language unrelated to anything nearby. As a slot theme, it's basically uncontested - nobody else has touched it. The reels sit inside weathered stone slabs against green highland foothills, Mount Ararat glowing pink on the horizon. Card symbols are chiseled into the stone rather than overlaid, and the premium icons pull from historical Urartian art: a bearded king in a pointed golden helmet, a noblewoman in a red headscarf, a winged lion-griffin, a bronze spearhead, a spiral sun-wheel, and a scalloped shell medallion.

Ten selectable paylines on a classic grid. The Wild is the sunrise-over-Ararat symbol, and it doubles any win it substitutes into. During the 15 free spins (triggered by three or more golden pendant Scatters), all wins carry a 3x multiplier - so a Wild substitution in free spins pays 6x. Free spins retrigger if three more Scatters land mid-feature. At base bet, Bonus Pop skips straight into those 15 free spins with the 3x multiplier active. Pricing scales with bet size, and the option disappears depending on your operator's jurisdiction.

The Risk Game after any base win is a card-draw double-or-nothing: pick one of four face-down cards, beat the dealer's card, your win doubles. A Joker card is available only to the player, never the dealer. Equal values push. You get up to 10 consecutive attempts on a single win, though the expected return on each round runs well below 100%, so repeated use bleeds your balance over time.

Endorphina's catalog-wide progressive jackpot system was added retroactively in 2023. Minor, Major, and Grand tiers trigger randomly on any spin, weighted toward higher bets. Jackpot winnings can't be gambled in the Risk Game.
