Once you receive another person's drawing, you'll have to guess what they meant to draw. The strokes will appear in the order they were first executed. If you do not wish to see a step by step, you'll be able to see the finished drawing by tapping on the button at the top right section of the canvas.
Beneath the canvas, you'll find the number of letters the word has and, at the top, the category it belongs to.If you guess the word correctly you'll get coins, a chest with different rewards, or both. You'll be able to receive coins up to 20 times a day and as long as you have space in the chest bar.
