board game

Too many possibilities.

Way too much guessing needed, with no obvious pattern to go off of.

For 2x2 block
last row second col, up
4 & 5th col block at r6c13/c16
should left 6 block at col 1,3,6 to play with.

For the 9 2x2 blocks on the left:
Up, up, down
Down, up, down
Down, up, down.

Good hint Ekkonic.

Thank you Ekkonic.

Logical with Ekkonic's hint! Thanks Ekkonic :)
