I always reach all the goals, but most games I uninstall after reaching the goals. Shooter was the last one, after I had reached the 10.000 goal.
I don't even know what was my first TL game, but I still play Fashion story 1, farm story, restaurant story and bakery story. I still have Per Shop story and Mystery story, basiscly because both games have no way to make gems in game. In Slots you get no reward at all.
It does work, tho I'm still waiting for offers for some of the TL games. Fantasy forest didn't charm me at all, I deleted that game right after reaching the goal. I had expected that I would like home-decoration, but deleted that one as well.
Only spent real money on Dragon story and Caste Story tho.
