• Today is the hottest day of winter

Do you want to know why?

Because we just released a brand new CheckiO section called Hot.

Hot is where we collect the hottest, freshest and most interesting solutions from the CheckiO game. Back on popular demand, you can now see this section starting with level 5.

Only solutions and comments you have access to will be shown in the Hot section. So while you solve more missions, more hot solutions will be shown to you in this section.

On top of that...

We also made some new UI improvements you were asking for.

  • Last mission you were working on is shown on the left menu
  • Quick following function on comments and solutions page
  • On Station Page, you can seen which missions you haven’t opened yet

One more thing… We have Awesome Account Gifts until the end of year 2016. You can send a gift to your friends with a pretty nice discount (-60%) to ring in the new year!

Happy holidays,
