This is a life counter for a 4-player Magic card game with Marvel heroes. Each hero starts at 40 life. Tap the green + to add life and the red − to take life away. The +5 and −5 buttons jump by five. Type a number in the little box and tap its green + or red − to change life by that amount. The ☄️ Snap button cuts everyone's life in half, just like Thanos. When a hero hits 0, they are out.
