Thinking did well for me.
In my primary, I got the full calendar with no diamonds with good strategy and math. I waited for days that had a calendar piece. Didn’t work super, but it kept up and I saved lots of doubloons that I spent on the last 5 days to secure those pieces. I spent about 3200 diamonds to secure 3 CartoHouses and spent $10 for the extra 200 diamonds I needed to purchase. The extra diamonds were if I needed more calendar pieces, but didn’t. I built the full building and will leave the second at lvl 9, for better production. Have 6 extra pieces, so maybe 30-40 days for the next. Lots of extra fight for what’s coming (Bye, bye GbG farming?)
In my diamond farm, just looking for CrowsNests. And 32 pieces, getting the last 2 with those spare diamonds, made for 4 more CrNests.
Swish!
