Thank you for organizing and publishing this tournament! All results so far are as expected for me, but let's see, perhaps there are surprises in the last round.

Hi Samueldora,

yes, this tournament pretty much confirmed the results of the previous months. It will be interesting to see how relative playing strength develops on Scratch 3.0. At least for Game of Kings this depends on the performance of the underlying Scratch runtime. I had to adjust two things due to Scratch 3.0 performance bottlenecks, now GoK is at the same level as on Scratch 2.0, or slightly better.

Samueldora

Hi, ArnoHu,

congratulations to GoK and to you for winning this tournament!

Thank you, Bonsai did well again too! Let's see what Scratch 3.0 will bring. I just noticed that Midecah Chess finally works there.
