The fantasy world and the card world came together to create the game BattleJack. You will play according to the rules of Black Jack and first choose your warrior. There are currently two candidates to choose from. They have different levels of strength, and this is important. Then, take turns with your opponent, throw away the cards; if you get 21 points, this is an unconditional victory. If it turns out more, your blow will remain ineffective. Anything less than 21 will allow you to attack and you will take away some of your opponent’s strength. You can replenish your strength a little with potion flasks in BattleJack. But remember that you only have five bottles of potions. Buy upgrades for your warriors.
