This will be a short guide for the teaser game, TSYKIAL, in case you haven't figured out how to solve it. Let's get on with it.

-------------------------------------------------------------------

Infront of you there will be 4 red buttons. Occasionally, there will be codes flashing on the screen for a split second. I recommend recording your screen with your phone or a recording software. Anyways, by pressing the down arrow, you can go behind you there will be 3 more buttons that are red, green and blue.

-------------------------------------------------------------------

By using a code there will be a set of numbers and letters. The 1,2,3 and 4 indicate the buttons you need to press. For example, 14212 you would need to press the first button, then fourth, then the second and etc. For G (green), B (blue) and R (red) you need the press the button behind you accordingly. And for the final step, the number between the brackets you need to use your number pad. If you need to reset, you can press Enter.

Well I think that's about it. Hopefully this guide helped you. If you have any other questions you can ask me in the comments!
