4 September 2014 announces the arrival of a new Knock-type building to Klondike - the Rainbow.

  • Get a Rainbow at the Market, place it on the ground and wait till your friends leave some sparkles in it so that you could upgrade the building. Later, you will get to transform your Rainbow into a heap of gifts. The more you upgrade the Rainbow, the better gifts you will get.

Initially, your Rainbow will look like a simple frame with a star, but as you upgrade it, it will keep improving and getting more and more beautiful.

  • The Rainbow has 8 upgrade stages, for which you will need: 1) 5 sparkles, 2) 10 sparkles, 3) 25 sparkles, 4) 50 sparkles, 5) 100 sparkles, 6) 150 sparkles, 7) 250 sparkles, 8) 77 sparkles.

Here are some details about the Rainbow:

  • In order to accept your sparkles, go to your Rainbow and click the green tick mark under your friend’s gift.
  • In order to gift sparkles to your friends you need to visit their Rainbows.
  • In order to send sparkles to those who have sent them to you, go to your Rainbow and click the Gift Back button. If you want to send a free sparkle, click the Visit button to the right from the Gift Back one.
  • Remember: you can only send 100 free sparkles a day, each one to a different person.

If a free sparkle is not accepted during 12 hours from sending, it disappears.

  • Once your friends start to accept your sparkles, there will appear a blue postbox icon in the right part of your game screen. Inside the box, you will find the return gifts sent to you when your friends accept your sparkles.

Note: the bigger pack of sparkles you gift, the better return gift you get.

  • Don’t forget that Rainbow season will end in 2 weeks’ time. After that, the gifting of sparkles will be over and the Rainbow will disappear from the market.
