Mines is my favorite game for quick sessions and the trick is definitely greed control. I usually stick to 3 mines and cash out after 4 or 5 tiles. I play this mostly on https://cobaltlab.tech/miner and it works great because the response time is instant. There is nothing worse than a delay when you are clicking, but this site handles it perfectly. The design is very clean so you can focus on your pattern without distractions. It is a great way to turn a small amount into something bigger if you stay disciplined. Just don't try to clear the whole board or you will definitely regret it. For a smooth and fast mines experience, this is the best spot I have found.
