Why is the Battery Icon Blinking Red

A red blinking battery icon indicates that the board has entered into a low power state and requires recharging. Before it enters this state the board will turn the icon a solid red to warn the user that the batter is low.

Don't worry though. If the board enters the low power state the game state will be saved just in case the battery dies. The game can be resumed after plugging the board in to charge. To resume the game make sure all the pieces are in the same location as they were when the board entered the low power state.
