In Calotank’s free calorie quiz, guess which of two foods has more calories. Each comparison uses 100 grams of each food, so there are no portion sizes to calculate. Play in your browser without signing in.
How to play
Choose the green or orange option within five seconds. A correct answer adds to your streak and brings up the next pair. The first wrong answer or running out of time ends the game. Each run has up to 100 different comparisons. On a computer, you can also use the 1 and 2 keys.
Challenge a friend to the same run
Share a challenge link from your result. Your friend gets the same food pairs in the same order. Your personal best is saved in this browser only.
Where do the calorie values come from?
The food data comes from THL’s Fineli database. Values are averages per 100 grams of edible food. Relevant preparation details appear with the food name. Calorie content alone does not describe a food’s nutritional quality.
