Can You Solve This Ice Cream Cone Riddle?


How much is an ice cream cone worth? In this visual riddle by Budapest-based artist Gergely Dudás (who posts comics on, 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.

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.

This 1980s Copy of Super Mario Bros. Is One of the Most Expensive Video Games in History

The original Super Mario Bros. changed video games forever when Nintendo released it for the NES in the 1980s, and now it's making history again. As The Verge reports, a mint cartridge from 1985 just sold for $100,150, breaking a world record in video game sales.

Super Mario Bros. was the first game starring Mario that Nintendo released for a home console. Most old copies of the game from the 1980s show noticeable wear, but the item that just sold through Heritage Auctions was a rare find for collectors. The cartridge is still preserved in its sealed case, earning it a "near mint" grade of 9.4 and a A++ "seal rating" from the rare game certifiers Wata Games.

It's also a rare "sticker-sealed" copy that Nintendo created for an exclusive test market launch of the NES in New York and Los Angeles. That, along with the game's pristine condition, helped make it the most expensive graded game ever sold when a group of collectors purchased it for $100,150 at auction.

Super Mario Bros. helped launch a video game franchise and paved the way for some of Nintendo's most famous properties, including Mario Cart and Super Smash Bros. It's one of several old-school NES games that collectors are willing to shell out big bucks for. Stadium Events, the 1990 Nintendo World Championships (one sold in 2014 for $100,088), and the Nintendo Campus Challenge are also very rare and expensive.
