Mahjong is not a slot that can give big wins. I have stopped making mahjong my favorite game because I get countless FS at bet 20k idr but the win is not too big at all, there is only one chance to reach 8 million and that is the worst thing if you make mahjong your favorite game.
You get below 100x? or just around there? believe me that I've ever gotten the worst, when I tried a bet of IDR 50,000. Got a bonus round, and at that time I thought I would get my first big win in Mahjong Ways. But what happened? Those 12 spins were even completely empty, no connection occurred in all the spins I got.
But I don't think that this game is cheating, it's a natural cycle that happens because we're just unlucky. The next day I tried again with IDR 300,000 and managed to get IDR 12,000,000+ from that small money.
