Riad, thank you for the very interesting tasks! As always, your assignments are simply unique! Sorry, I did not have enough time to show a more decent result. It's amazing that you noticed my flaw on MAXIDOMINO (replacement 1 and 2) - thanks for the reward! And it is surprising that you didn’t notice my failure to refine PENTOCOLOUR (replacement of black L and V), which would give 37 and +6 points to the final table. This is how your appetite for your attentiveness grows!) I apologize that it may have frightened someone who counted himself 74 in PENTOCOLOUR - does the orange color of pentamino are so much worse than black not to count orange?) I'm already looking forward to your new habitually unusual and interesting tasks! Thank you for the good work!

I would like to thank Riad for beautifully though contest, as usual. :-) My favourite pieces were Sumino and Dice Masyu, meanwhile, I broke twice the Crossword because I did not realize one extra possible combination at the top of the puzzle. In optimization I am still such a beginner, but we will see next time. :-) I am looking forward to it. Thanks once more.
