That was a great contest with beautiful Tapas! Thank you!
And the contest was very well doable just with the mobile phone, even the 20x20 puzzle.
In future it would be great, if there is more time to solve the puzzles, i.e. every 30h a new puzzle but the puzzle counts during the next 5 days, since not everybody has time to solve them on a daily basis.
As IHNN already mentioned, the scoring A for 1-100 rank is in my opinion suboptimal, because, luckily, of the high number of participants. It would motivate more if each participant get some points and not only the best solvers.
The replay button is a great feature to learn from the top solvers or just to see the different approaches.
I‘m looking forward for the next puzzle types :)!
