Two stupid things; 1, level up animation. Please buy some glasses for whoever come up with that idea so he can notice it even its minimised at some corner on the screen. 2, choosing slot to unlock which is unnecessary. Please ask the person who programming if they having mental issue or something. Only biggest idiot would play all those unlocked slot whenever they pop out at the screen. Extra note, both are repetitive which is bothersome & annoying. Last, INCREASE BET VALUE.
