So probably most of you already know about this game, but in this video i present you a strategy that works 80% of the time.

The key is to memorize patterns of empty boxes, the biggest probability to win is to free bet 2 times, memorize a box that stayed empty for both times and most likely it will be empty for the third time when you place your bet. It is not a guaranteed winning, but i've earned nearly 16 BTC with this technique throughout the period of 1 month
If you play with my referal link and lose an amount of BTC, you can PM me on youtube and i will return 10% of your lost BTC,
