Parent Pro-Tip

Parents should be aware of the simulated dangerous activity (knife game) and reinforce the in-game warning about not attempting to replicate it in real life. The game is good for quick bursts of play and developing motor skills, but has limited cognitive or social benefits.

What your child develops

4 Fingers primarily enhances motor skills, including hand-eye coordination, fine motor control, and reaction time. It also demands sustained attention and offers an adaptively challenging experience as the knife's speed and unpredictability increase. The game can also help develop emotional regulation due to the 'nerves of steel' required.

About this game

4 Fingers - the game requires a good reaction and nerves of steel. You have to beat the knife between his fingers, and the knife will gradually accelerate, which further complicates the problem.
