I enjoy this game and do recommend it. I also commend the creator for his or her efforts. But there are issues.
The "Bot" opponent is not supposed to be able to play dark blue, or locked, tiles. Yet this frequently happens.
The "Bot" players occasionally come up with wprds that don't exist, while I am occasionally )once everytwo games on average) am not permitted to use legitimate words.
Often, when one passes the cursor over tiles, they shift to an odd angle or are moved into the line where one spells new words, without clicking on them. This happens multiple times per game.
Occasionally, when the "Bot" player cncedes, the game is still counted as a victory for the "Bot/"
I hope the developer(s) can fix these errors as they do detract from the overall enjoyment of the game. But I will keep playing nonetheless, as long as it remains free.
