220 Blanks, from what I gather that will be impossible to improve on.
After looking at numerous different ways to attack the problem of blanks many solutions lack symmetry. So a tip for thoose who wanna atleast try and get past 200.
with symmetry comes efficiency and many blanks. All thoose who have 171 in score started with all red and exploded somewhere in mid. but 18x18 beeing an even number means you have to time the explosions in other words delay the corner one square closer to the edge since any even number square has four middle peices instead of 1.
After coming to this conclusion you'll be on your way.
Btw I should get a fricken badge for this one ;P
Something shiny with my name on it n a party hat n a six pack of beer.
Hmm.
And a hat with a bunny in it.
Hm... Think I'm done with this game now... My eyes bleed and my fingers hurt from all that clicking but all in all it was an excellent brain excersise.
Each day a new thought and a new strategy. 195 Blanks will not be easy to beat.
GL n have fun.
