Sky Stack
Build the tallest tower, one right word at a time. A quick English game set in a city of tall buildings, with one simple action and real English in every move.

How to play Sky Stack
- A new floor slides across the top, changing its word each time it turns.
- Read the sentence at the top.
- Tap when the floor shows the right word and sits over the tower.
- Line it up exactly for a Perfect. Miss the edge and the tower gets narrower.
What English it practises
Students must both recognise the right word and time the tap. Sentences are about builders and buildings and cover the tenses for their grade.
How it helps with studying
The goal is simple: build higher than last time. To do that, a student has to answer again and again, so practice grows without being asked for.
