Animal weights: compare, play and learn
The Cardsimals Weight challenge turns a common question —“how much does this animal weigh?”— into a daily game. You get eight cards, three lives and a line to build from lightest to heaviest.
We do not use a record maximum or a random number. Each card has a representative weight tied to a specific biological context so comparisons stay coherent and repeatable.
Frequently asked questions
What is Cardsimals?
Cardsimals is a daily animal game built around ordering eight cards. Weight compares body mass, Conservation ranks species by threat level, and Names sorts them alphabetically. Each mode shares the same learn-by-playing idea while using its own data and rules.
How does the animal weight game work?
The first card is already placed. You receive one new card at a time and decide whether it belongs before, between or after the animals already in the line. A correct placement reveals its weight; a mistake costs one life and lets you retry the same card.
How much does an animal weigh, and why is there not always one answer?
Body mass can vary with sex, age, population, season, condition and, for domestic animals, breed or type. That is why a search such as “how much does an elephant weigh?” usually returns a range. Cardsimals needs one gameplay value, so it uses a representative weight that matches the card context.
What does “representative weight” mean?
It is the value Cardsimals uses to order a card in the challenge. It must be biologically consistent with the animal shown and the reference data available. It is not a claim that every individual in the species weighs exactly that amount.
Why do some cards specify male, female, adult or a particular type?
When sex, life stage or variation meaningfully changes expected weight, the card can show that context. This avoids comparing a value for an adult male with a label or image that suggests a different biological case.
How is the data reviewed before it is used?
Curation separates scientific data from gameplay policy. Units, ranges, context, sources and representative values are checked independently. The generator also avoids making a Normal challenge depend only on extremely close or ambiguous comparisons.
What happens if two animals have the same weight?
Equal Weight values are equivalent. There is no secret ordering based on animal ID or name. If two frozen cards share exactly the same value, either equivalent placement should be valid.
Can I play more than one challenge per day?
Yes. Every day includes Weight, Conservation and Names. The Archive also lets you revisit available past challenges without changing the frozen answer for the original date.
