About this game
Eleven pairs that make twenty on one board — the bigger sibling of the bonds-to-ten deck. Study the layout, then find each pair from memory as it's called.
Study tips
- Say each tile aloud as you study — sound gives your memory a second anchor.
- Group tiles into little stories or zones ("top row is the warm colours").
- Replay the same level until you get a Flawless run before moving up.
Frequently asked questions
How does the Number Bonds to 20 recall game work?
The tiles are shown for a few seconds — memorise where each one sits. They then hide, and the game asks for each one in turn. Click the right spot to reveal it; wrong clicks count as misses.
