Birthday Celebration [ENDED] [SOLUTION ADDED]

Hello,

Today is my birthday Saturday was my birthday and I wanted to celebrate it. I've been here for about 3 months and I'm so happy to have met so many wonderful people. So, thank you very much (less to the ungrateful).

I have created a puzzle that when completed will give you access to a train. Games are secret, but they're not bad at all ;)
I'll try to give some hints if I see that there aren't many participants, it's my first puzzle and I hope I did well, but there shouldn't be any problems to solve it.

Some info:

• There is a total of 11 14 GAs
• All of them First 11 are LVL+6 and last 3 are LVL+0
• End on 29/05 at 12 CET
• Don’t share any of the GA links

I want people join GAs of the games they are going to play, not +1.
I got the games a few weeks ago, so I'm not sure if they work. If so, let me know so I can replace the key or delete the giveaway.

Start here SOLUTION

Good luck!

P.S. Maybe I'll add people to my whitelist and make some more GAs

HINTS

• Each wire's down direction is the border segment color it corresponds to.
  • This hint indicates that, for example, if the red border is at the bottom of the image, the wire/form/angle (don't know how to call it) of the matching color is in the correct orientation. Rotating the image can make it easier to see all the wires in the correct orientation. It's not necessary to move the wires, just know how to interpret them.
• Each wire is a letter, you just need to know how to decode it.
• The colors are only to determine the order. Follow the rainbow!
