I agree with players who already pointed out that the mode of obtaining rubies is absolutely ridiculous. Even the mini game gives you a false hope and lets you win the first time you spin. Spins after that are just pure luck. Also with so many story games already released, you should really charge a one time payment. Other than that, it's just 'money grab' system. I do not get it how majority of your games retains the score so high (4.7>) if you can't offer a better way for premium choices.
