Aztec’s Millions is a classic-looking slot from Real Time Gaming, where each line costs 0.20 cents. It is not a typical slot game because you cannot choose the number of paylines or bet size. You’re obligated to pay 0.20 cents for all 25 lines, meaning that you will pay 5 euros for each spin.

This type of gameplay and the game’s aesthetics are usually preferred by older Irish players. The game is easy to understand and the rules are easy to find all the time. If you decide to try this popular game, mind that you can trigger the progressive jackpot only with five Aztec’s Millions symbols on the screen.
