Our YuGiOh Score Keeper app is extremely useful if you play the Yugioh card game. We have built in a small calculator to help do simple math if you need it, as well as a "Roll the Dice" and "Flip a Coin" to make plaging the game much faster and less messy. You can also set player names and starting life points to customize your app experience. Please contact us at support@darkdroiddevs.com to give us your feedback and request features!
