It’s a casual puzzle game. The basic idea is this: Form complete chains to remove blocks from the board. If the board fills up, you lose.
Here is the free version:

I’ve used only interstitial ads when starting a new game…hopefully users don’t find these too imposing.
There is also (of course) a paid version with no ads:

My laptop is too slow to use emulators, so I’ve really only tested one device. If anyone wants to give the free version a try, I would love some feedback.
Here’s a gameplay screenshot:
