Stumbled across another tiling spin off site. Squadrats
Guess its hard to find a new URL name.
https://squadrats.com/Has some uses in showing just how many new tiles you bagged for a ride. The rest of it is a touch baffling on first look.
My latest ride filled in a nice chunk of cluster and got me 33 new tiles.
Trying to work out the colour code:Full green tiles are new ones grabbed.
Initially thought that the shaded green are those that now join your cluster, but it appears not that simple.
White is my current cluster
Grey are uncollected tiles
The description for Squadratinhos is interesting:
"Tiny Squadrats 64 Squadratinhos make one Squadrat,
Come and get all of these small nasty bastards"
Guessing Italian origin maybe.
