Have given 1 star as no option for zero, been playing for about 3 years, was on 358 level, just used in spare time, but froze and wouldn't let me play, reinstalled and started again, worked fine for a week then exactly the same problem, uninstalled for good, writing this review before uninstalling, New people do not waste your time, absolutely disgusting app, the score I would leave is 0 0 0 0 0, no stars.
