It is a very addictive game in the play store.first I download it 1 years ago.and now my level is 726.it was not easy to complete hard level, super hard level.however my mom is also being addicted with this game.there are many boosters to complete a level easily .this game develops your brain .there are more than 2000+ levels in this game.I want to complete all levels.but every thing in this world has a bad effect .however it is a well time passing game , it wastes our valuable time .so don’t addict with this game. But don’t leave this game.
