Guide
Block puzzle online game free
This search usually means a free classic 8×8 three-shape puzzle you can try fast. Browser games work for a quick session; the offline app is better when you want dig-layer depth without wifi.
What people mean by online free
Most results are browser embeds of the same place-three-shapes loop. They are fine for a five-minute try. They often need a connection, rotate ads, and rarely keep a dig-layer progression between trays.
When the offline app is the better answer
Install Deep Blocks (store name Block Puzzle Offline Dig) when you want no-wifi play after download, an untimed calm session, and a mine layer under every cleared board. The store title leads with block puzzle + offline so the listing matches how people search.
Honest next step
Try a browser tab if you only need an instant sample. For travel, flights, or longer runs, install the official iOS or Android app and dig offline.
Play the offline dig-layer version
Free on the App Store and Google Play. Classic 8×8 block puzzle with dig layers—no timer.
