Even while the 6 Jewels slot doesn't look like much on the outside, there's a lot more action happening behind the scenes. Features like expanding reels, free spins, multipliers on wins, cascading reels, and more provide an excess of value.
The game's cheerful host, Miki the alien, sits on the left side of the screen. He occasionally flies across it, and when you fulfil specific conditions, he triggers reel modifications and additional features. A gigantic 5x5 grid serves as the stage for the events, and as the game progresses, it grows increasingly larger, eventually extending to an incredible 10 rows. When you start off, they're locked but as you win, they unlock giving you better chances to win.
Unlike Cluster Pays, which awards wins in any direction, the 6 Jewels slot machine only pays out in straight lines. To win, you'll need to line up at least three identical symbols in a row. Winning combinations can be as much as ten symbols in a vertical row and five in a horizontal one. As promised, the pay symbols consist of six jewels of varying colours and forms; winning combinations of five of a kind award 2x to 5x the stake, while winning combinations of ten of a kind award 500x to 800x. The satellite symbol is a Wild that can replace any other normal symbol. It pays out for two of a kind or more and can award 1,000 times the bet when you get ten of them on a payline. But, as you'll see below, Wilds only show up during wins and extra features.
The Free Spins feature is activated when three or more Portal symbols appear anywhere in view. Starting with 8 spins, players can get an additional spin for every additional Portal symbol. The bonus game is quite similar to the main game, with the exception that there is a greater possibility of winning and better Multiplier values: 3, 5, and 10 times. In addition, you can win an additional 250 times your stake if you clear the full grid during the free games. And lastly, retriggers can be activated with a maximum of 55 free spins being achievable.
