GAMES THAT KEEP YOU SHARP

Short puzzle games that give your brain something to do — free, instant, and playable on any phone or laptop. No download and no signup. Every game says right up front what it exercises, so you know what you're getting into.

Pairs of numbered tiles drop down. Any line of touching tiles adding up to ten vanishes — and whatever falls into the gap can set off another match.

What it exercises Instant recall of pairs that add to ten. Spotting them is the only way to play, so the arithmetic gets practised rather than tested.

Food Rescue

🍎 Food Waste & Sorting

Food has been left all over the kitchen. Pick it up and put it away — anything still good goes in the fridge, anything that's just scraps goes in the bin.

What it exercises Telling food that's still good from food that's finished with. You carry each item to the fridge or the bin, so the decision is the move you make rather than an answer to a question.
