How much is an ice cream cone worth? In this visual riddle by Budapest-based artist Gergely Dudás (who posts comics on Dudolf.com), the answer requires a little math.

The riddle asks you to determine how much an ice cream cone, a scoop of white-colored ice cream (let’s call it vanilla), and a scoop of pink-colored ice cream (let’s call it strawberry) are worth, according to the logic of the puzzle.

Stare at the equations for a while, then scroll down for the answer.

Ready?

Are you sure?

OK, let's walk through this.

Three ice cream cones multiplied together are equal to the number 27. Since 3 multiplied by 3 multiplied by 3 equals 27, each cone must be equal to 3.

Moving on to the next row, two ice cream cones each topped with a scoop of vanilla ice cream added together equal 10. So since each cone equals 3, the vanilla scoops must each equal 2. (In other words, 3 plus 3 plus 2 plus 2 equals 10.)

Now, a double scoop of vanilla on a cone plus a single scoop of strawberry on a cone equals 11. So if a double-scoop of vanilla equals 4 (2 plus 2) and each cone is equal to 3, the strawberry scoop must equal 1. (Because 4 plus 6 equals 10, plus 1 for the strawberry scoop equals 11.)

And finally, one vanilla scoop on a cone, plus one empty cone, plus a double-scoop of strawberry and a single scoop of vanilla on a cone, all together equals 15. One scoop of vanilla on a cone is equal to 5 (2 plus 3), and an empty cone is equal to 3. Two strawberry scoops plus one vanilla scoop plus one cone can be calculated as 1 plus 1 plus 2 plus 3 (which comes out to 7). So together, one vanilla scoop (5) plus one cone (3) plus a triple scoop with two strawberries and one vanilla on a cone (7) equals 15.

And there you have it.

A cartoon-style legend that shows that one cone equals 3, one white scoop equals 2, and one pink scoop equals 1.

Feeling Stressed? Playing Tetris Could Help Relieve Your Anxiety

When Nintendo released their handheld Game Boy system in the U.S. and Japan in 1989, the first game most users experimented with was Tetris. Bundled with the system, the clever puzzler—which prompts players to line up a descending array of tiles to create horizontal lines—was the video game equivalent of an addictive drug. Some players described seeing the shapes in their dreams. The game was in the hands of 35 million portable players; by 2010, it had sold 100 million smartphone downloads.

Now, there’s evidence that Tetris players may have a solution to anxiety in the palms of their hands. According to a paper published in the journal Emotion, Tetris has the capability to relieve stress and troubling thoughts by providing a form of distraction.

As part of a larger study about the benefits of distraction, researchers at the University of California, Riverside conducted an experiment on 309 college students who were told to expect some anxiety-provoking news: They were told someone would be offering an evaluation of their physical attractiveness. While they waited for their results, a third of the subjects played a slow-moving, beginner-level version of Tetris; another group played a high-speed variation; and a third played an adaptive version, which automatically adjusted the speed of the game based on the player’s abilities.

Tetris games that were too slow or too fast bored or frustrated players, respectively. But the game that provided a moderate challenge helped reduce the subjects’ perception of their stress levels. They reported a quarter-point higher level of positive emotions on a five-point scale and a half-point reduction of negative emotions. The students still worried about the results of the attractiveness evaluation, but they experienced fewer negative feelings about it.

The key, according to the study, is that the students were experiencing “flow,” a state of mind in which you’re so engrossed in an activity that you lose your sense of self-awareness. While Tetris may be one of the best ways to quickly fall into flow, anything that consumes your attention—playing music, drawing, cooking—is likely to work.

The next time you have to wait for potentially life-altering news, you may find that a Tetris session will help you cope.
