About the Numbers Spot the Difference Game
One, two, three, four — our numbers memory game makes early counting practice fun and engaging. Bright number cards help preschoolers recognise numerals while building essential memory skills.
What's on the Numbers boards
The pictures the two boards are built from — 12 in all: 1️⃣ One2️⃣ Two3️⃣ Three4️⃣ Four5️⃣ Five6️⃣ Six7️⃣ Seven8️⃣ Eight9️⃣ Nine🔟 Ten0️⃣ Zero🎯 Target
Study tip: scan the left board in the same order every time — top-left to bottom-right — and check its twin against that order. The difference between one and two is easy to spot; a missing three in the wrong corner is not, unless your scan is systematic.
How to memorise a learning deck
Learning decks — letters, numbers, colours — are the ones to play with your voice. Say each item out loud as you study the board: the label, not just the symbol. Spoken repetition loads both the visual and the phonological memory systems at once, which is exactly the double-encoding classroom practice relies on.
Test recall by naming, not just matching. After the board hides, ask "which letter was next to the butterfly?" — questions like that force retrieval, and retrieval is what turns a quick game into actual learning. Matching alone can be done on autopilot; naming cannot.
How to Play
- Press Start. Two boards appear, looking identical.
- Compare them tile by tile — one has been swapped for something different.
- Tap the changed tile, on either board, before the timer runs out.
- Each round adds more tiles and less time. Three misses ends the run.
Fun Facts About Numbers
- The concept of zero as a number was invented in India around the 5th century.
- The ancient Babylonians used a base-60 number system — we still use it for time.
- The number "googol" is 1 followed by 100 zeros.
- Pythagoras believed numbers were the building blocks of reality.
Learning deck questions
Can these decks help with reading and counting?
As practice, yes — matching uppercase to pictures and saying letter names and numbers aloud reinforces what phonics and counting lessons teach. They are a supplement to teaching, not a replacement for it.
Which board should a five-year-old start on?
Easy — six pairs. The win rate matters more than the challenge at this stage: a child who beats the easy board three times will march to medium on their own, and one who loses hard boards twice will not.
