I've been enjoying playing Rikudo Puzzles on android - https://play.google.com/store/apps/details?id=com.rikudo.numbers
It's like Simon Tatham's Signpost game, but on a hexagonal grid. You have to place numbers in the cells to form a contiguous path which fills the entire board. I don't get much out of the timer and stars for finishing quickly - I just like solving the puzzle. Placing numbers can be a bit fiddly - it's very easy to accidentally switch to counting backwards, or miss out a number.

I dreamt that it was possible to draw this in one go without lifting the pen. It involved folding the paper somehow.
It isn't possible, is it?
Never mind screen time, at the moment we're having to limit the baby's lamp time. No idea what's so entrancing about this lamp. 🤔
More mathematical sights on holiday. Beginning to wonder if I'm part of a word problem.
Hands of bananas, helpfully labelled for those who can't count?
Geometers HATE this one weird trick for drawing a hexagon!
