Once you get past level 50, it's impossible to be successful – Classic Lemonade Stand Review

The cost of supplies increases everyday, but you won't sell anything if you charge more than $5. Even at $5 you can only sell one lemonade per day, so you can't break even in the higher levels. I made it to level 165 where the cost to produce one lemonade was $10. I could only charge $5. I tried the strategy of stocking up on supplies while the cost was still low, but cups blow away, lemons spoil, and sugar gets bees, so the cost of inventory can't be recovered. It was fun at first but quickly got boring.
