The best
Definitely the best in this series! Sooo good! Should be a paid for game! This developer is not only talented but unbelievably generous. A lot of free games are purposefully created with illogical puzzles to encourage advert watching for hints which loses enjoyment but this series is a definite exception, the puzzles are perfect and completely logical giving the player so much satisfaction on solving them, I paid to remove ads because this developer should be rewarded and I hope others do this too.
