Piano Tiles is made in white and black tiles layout, sort of like an elongated chessboard where you can play in various modes such as Classic, Arcade, Zen, Rush, and Relay.
In order to play this game easily, use two fingers so that you can divide the board into two pieces and you can allocate one finger for each move
On the other side, to optimize your tapping, you can use with your left finger where you can tap the tiles on the first two rows which are from the left and the right one coming to left for the final two.
Anyway, alternating the tapping and using a finger for each new tap will be difficult when you have your left hand on the fourth row while you have to jump over it with your right one to tap the first row.
Furthermore, if the two index finger method is not working, you can try to find something new that works the best.
