What do Casinomeister, Ariana and Thunderstruck II have in common? It sounds like the beginning of an iGaming developer’s joke, told across the embers of campfires as hardened gamers share stories of popular glories past. But it is no joke. This is serious gaming talk. A Casino Kings brain teaser.

You may um and ah. Casinomeister hails from Next Gen Gaming’s Aussie studios, while Ariana and Thunderstruck II spawn from Microgaming’s heaving bosom. No link there.

Bonuses? Ariana features Stacked Wilds in an underwater paradise and Thunderstruck II‘s Wild Storm feature brings Wilds whirling round like Thor’s hammer…but Casinomeister‘s main feature is its Unlimited Free Spin bonus game. No dice. In fact, we have already touched on the answer.

Regular Casino Kings players will kick themselves. You’ve probably played all three titles recently. Another hint. Okay, I’ll put you out of your misery. [sigh]

All three games regularly feature on the Casino Kings Most Popular lists. Ah! You have a dog and his name is Bingo!

Which is why you’ve probably played all three titles very recently. (The fact that these games are some of the most popular, not the fact that you’ve just acquired a dog called Bingo.)

We’ve already mentioned some of the bonuses that make these games so popular. Unlimited Free Spins out of the clutches of the evil pig, Vortran? Yes please! But we’ve yet to mention the gameplay.

Casinomeister pays obvious (but not copyright infringing) tribute to hit sci-fi franchise The Matrix, Thunderstruck II draws on the legends of Norse mythology with awesome artwork and animations, while the majestic beauty of the sea is captured perfectly in Microgaming’s Ariana.

These games are playable, fantastical and imaginative. No wonder they are continue to prove the most popular.
