6 consecutive raids give me One to Four Effective and discontinuous Tiles in the first three rounds of the each raid. What a bad idea on the game design. I think SG should design hero who can change the Tiles Color from the board if SG must be designed the game to be based on luck.
Otherwise I stop recharging all games and wait a month or two. If the game is still not improving, I give up and delete the game.
Finally, I paid $5,000 for the game, and finally I got a terrible experience. I really want SG Game Designer to go to hell.
