Two were thrown in 2010, and three were thrown in 2012. There have been only 23 perfect games in MLB history. To achieve a perfect game, a pitcher must record 27 consecutive outs without allowing anyone from the opposing team on base. Last week, due to all the no-hitters that had been pitched this MLB season, you looked at perfect games. Solution to last week’s Riddler ExpressĬongratulations to 👏 Chris Smith 👏 of Buford, Georgia, winner of last week’s Riddler Express. The solution to this Riddler Express can be found in the following column. What is the maximum product you can achieve?Įxtra credit: Zax the Mathemagician (no relation to Max) has the same routine in his show, only the wand has a length of 100. As he calls you up to the stage, you know you have this in the bag. You raise your hand to volunteer, and you and Max briefly make eye contact. If the product is the largest possible, they will win a free backstage pass to his next show. For example, if they break the wand near its midpoint and nowhere else, the resulting product is 5×5, or 25. After the volunteer chooses these breakpoints, Max will multiply the lengths of the resulting pieces. He has a magic wand of length 10 that can be broken anywhere along its length (fractional and decimal lengths are allowed). Max the Mathemagician is calling for volunteers. Please wait until Monday to publicly share your answers! If you need a hint or have a favorite puzzle collecting dust in your attic, find me on Twitter. Submit a correct answer for either, 1 and you may get a shoutout in the next column. Two puzzles are presented each week: the Riddler Express for those of you who want something bite-size and the Riddler Classic for those of you in the slow-puzzle movement.

Every week, I offer up problems related to the things we hold dear around here: math, logic and probability.
