Tumblers

Tumblers is a singleplayer game accessible through the EPF Phone. It is only available in certain Field-Ops.

Gameplay
Players must match the scanner to the correct frequency number. Players will have to stop it at the exact point, though it allows a little bit of differentiation.

Each player is limited to three lives, in which losing all three will result in the game ending.

Trivia

 * It appeared in Field-Ops 15 and 19.
 * According to many players when the game was first released, the game was difficult to beat due to the speed of the scanner.
 * Some also said that their scanner did not match with the frequency number despite the scanner matching near or on the correct frequency number.
 * Those who were able to complete it also complained that they were not given EPF Medals, while some said that their game froze.
 * The difficulty was lowered and the bugs related to progress were fixed a few hours afterwards.
