I've got some 4.4 diamonds, but they're not minimal(so i didn't save them). So I believe there must be some..

these appeared during testing after the game had closed. all stopped now. dont know if more mining would have found diamonds!

but they're not minimal

for this pattern {280}
the neighborhood search without minimality constraint
demonstrated fairly good results.

It is obviously impossible to have a 1.2,1.5 or 1.7 with two empty boxes in a band..
And I tried for a while to avoid 1.2 singles in the beginning and failed..
So this might be my only submission in this game, as I don't have any idea about any advanced technique.

. . . I don't have any idea about any advanced technique.

Have a look at this: Patterns Game Strategies for stategies past and present players have used.

This pattern is not productive! [like pg 0331!] - I have 2 diamonds (2.0, 2.3), nothing better than /2.5/2.5, and best so far is 9.0/1.2/1.2.

All I could get are 2.0, 2.3, 6.7 and 4.5 puzzles with EP=ED=1.2, and a 2.3/2.3/2.3 one.

I've answered in the Patterns Game Strategies thread here.

Thanks for your answer there! I haven't considered what would I do if I had a custom generator, and I am not planning to take this game so serious (at least not now ) Sometimes the pattern is really inspiring, then I would simply try something..
