Pay to play. No matter what your skill level is, they rig certain levels to be unbeatable without multiple boosters. 49 is the worst yet. Boosters caused the screen to freeze and then disappeared. I played because I saw the Poirot promo and that was smoke and mirrors, you don't play with the Poirot character or tropes at all. Not worth it, it isn't fun, you can't pay casually. Boo. One star is too many for hijinks like that.
