Order by weight, lightest first. You place all 35 cards in the right order, one at a time. You start with three lives, and ten right in a row wins a lost one back.
The cards are objects, from things that sit in a desk drawer to things you could only ever visit, and you put them in order by weight in kilograms. The line under each name tells you exactly what's being weighed, which matters for planes, ships and rockets. One object starts on the line with its weight showing. Slot each new card into a gap. A right call reveals its weight, and a wrong one drops it into its real spot and takes one of your three lives.
Everyday sizes are easy to feel in your hand, so the small end rewards plain common sense. The trouble starts once things get too big to imagine lifting. Vehicles, monuments and machines jump past each other in ways that can surprise you, and a hollow shape can weigh far less than a solid one that looks smaller. Read the small print, because fully fueled and empty are very different things. Think about what each one is actually made of.
Here are 28 of the 35 cards you might be dealt, with 7 more in the deck. Their values stay hidden until you place them.
