Recall2 - a memory improvement game

[PhilOfPerth]

version from 04-04-2023, 05:29 AM is erroneous

having guessed 2 identical ones, 1 square is filled in

plus, would have implemented obvious:
having reached edge, cursor be would be moved to other side

Yes, thank you Danilin; as bplus pointed out earlier, there were errors in that listing. These were corrected in my final post, 
and the programme appears to work perfectly as designed. The "obvious" change that you mentioned was one I had considered, 
but rejected in favour of having the cursor stop at the edge, as this made it simpler for the player to correct their over-stepping.
If you would like to try the final version, I would be interested to hear your thoughts on this.
