Optic Tuner

Optic Tuner is a clicker game where you can change the color of the main crystal by clicking on it. Your need to tune the crystal before the timer runs out. To do that, just select a hue that matches the sample. Each crystal is unique, so the sequence of colors is always different. To succeed, use all your concentration and reaction skills.
If you're having difficulty tuning the crystal in such a short time, try the bonus mode. In this mode, you can test your color perception skills. After a short demonstration of the sample crystal, you need to choose from the offered crystals the one that has the identical color. Sometimes the shades are hardly distinguishable, so you need to be extremely attentive. If you choose correctly, the time for tuning the crystal will increase.
