Hi Guys, @KingFredTheAwesome ,
Time for a new challenge:
Can you code 1 red, 1 blue, 2 r, 3 b, 5 r, 8 b, 13 r, aka the fibonnaci sequence?
Looking forward to your solutions!
Best regards,
Leo
Thanks for the nice challenge! It would be 13 red balls if there could be 21 balls at the beginning.
Regards,
Mia

@Mia, you nailed it! Great job! I can see in the emulator there is not enough red balls but you did it.
Can we create more nice challenges for each other? 
Turing Tumble
Thank you for the kind words. I would like to share challenges but I started with Turing Tumble last christmas, so I don‘t have much experience at creating puzzles. I created one related to your idea of the fibonacci sequence.
I Hope you enjoy it

My version starts with blue balls. It also intercepts the 22nd blue ball at the end.

Nice challenge, working on it
I did it @LeoMarble

There aren’t enough marbles but it would work if there were enough (if you take the red marble from the lever and replace it with a blue there are enough)(It can can by built on the real board)
