I imagine Gizmodo readers will not O.K. of a Luddite take , but I ’m going to risk my skin and wax nostalgic for strong-arm calendars . Do you think back Page - A - Day calendars ? Each sunrise you ’d shoot down a Sir Frederick Handley Page to disclose the newfangled engagement and some little reward for waking up — a comedian , a vocab word , a brainteaser ( ! ) . We used to enjoy advent calendars and sexy firefighter . Today , Google Calendar and Microsoft Outlook , with their sterile and ultra - pragmatic interfaces , have demote our playfulness to the obsolescent human race of gag gifts . Oh , your calendar client commit automated alerts to all of a meeting ’s attendees at the same time ? Sounds effective , but did it give you a piece of umber ?

Puzzle #3: Calendar Cubes

Two block , each with a single digit between 0 and 9 printed on each face , can be arranged in a bearer to display any day of the month as a two - digit act ( for example , 25 on Christmas or 04 on American Independence Day ) . How do these work ? If you were tasked with designing two cubes capable of showing 01 , 02 , 03 , … , 30 , 31 , how would you assign digits to their face ? This might not seem puzzling , until you set out to try . Remember that cubes only have six faces , so you have 12 total spaces to work with .

If you solve this and crave an additional challenge , how would you present the three - letter month abbreviation ( for example ‘ jan ’ , ‘ feb ’ , ‘ mar ’ , and so on ) with three cubes , in which each look contains a small letter letter ?

work out the numerical job first . The same put-on will amount in handy if you try the more difficult letter version .

The solution and a Modern puzzle will be posted here next Monday . Put it in your calendar . ( Update : you could recover this hebdomad ’s resolution and the following workweek ’s puzzlehere . )

Solution to Puzzle #2: Reverse Tic-Tac-Toe

Last calendar week , we asked you to sleuth out the past in everybody ’s preferred three - in - a - course game .

The tic - tac - toe position above was contact in a game between two flawless role player , meaning neither of them ever made a move that would allow their opponent to pull ahead by force and neither of them overleap an chance to force a win themselves . What were the last four movement played ?

I ’ve enumerate the squares for clearness ’s sake . The last four moves occurred in cellular telephone 6 , 4 , 8 , and 2 . Let ’s work through the reasoning . X move last because there are four Xs in the diagram and only three atomic number 76 . So what was X ’s last move ? Could X have played in cell 1 ? Well , if that had been an option , X would have bring in cellular telephone 9 rather and won the game ( retrieve , the players act as flawlessly ) . So X did not play in cell 1 last , nor did they play in cell 8 by the same reasoning .

The last move was either X in cellular telephone 3 or X in cell 6 . How can we contend that X did not play in cellphone 3 ? Because X still could have force a win by alternatively play in cadre 9 ! If cell 3 were empty , then prison cell 9 would simultaneously set up a horizontal two - in - a - row and a vertical two - in - a - row . O would be incapacitated to stop both on their next move . By cognitive process of reasoning by elimination , we have successfully deduced the last move : X in cell 6 . draw back that move , the placement looks like this with O having just played :

Now , what was O ’s last move ? It was not cellular phone 2 , because playing in cellular telephone 6 rather would have won . So O either play in cell 4 or 5 . Determining which requires us to take two more steps backward . Suppose O just play in cubicle 5 . This means the position looked like this , with X having just played :

Does something seem off here ? X just moved , but no matter which move of theirs we retract , X could have instead forced a win by playing in electric cell 9 . For exercise , if X had just play in cell 3 , playing in cell 9 instead would have set up bring home the bacon threats across the diagonal and the scummy row . Feel barren to gibe that X performing in prison cell 1 or 8 similarly give up a succeed chance in cadre 9 . By process of elimination , we reason out that O play in cell 4 on their third move , and the historical placement attend like this :

X could n’t have just played in cubicle 1 , because cell 9 would have forced a profits . cellular telephone 3 ca n’t be the answer , because cell 7 would have forced a win in that case . So X just played in cellphone 8 . This plants us deep into antiquity , with one more move to unlock :

What did O just play ? Suppose O just played in cell 5 . Then X could have force a win on their 2nd move of the biz by playing in electric cell 5 instead of in a street corner ! For deterrent example , if this were the position ,

then rather of X acting in cellphone 3 , they should act in jail cell 5 and the game will continue with O playing in cellular phone 9 ( to block the aslant ) , and X playacting in cell 7 , creating an unstoppable winning threat . So O play in cellular telephone 5 on their very first move of the game , and our answer is cellular phone 2 .

We ’ve now get a line the last four moves . That final deduction was a peculiarly tough one . Some of you may know perfect tic - tac - toe scheme , which aver that if X begins the game in a street corner , then O must play in the center to avoid losing . know this detail could have made the final gradation of this puzzle easier , because X only has marker in corner cell so O , being a unflawed player , must have played their first move in the center . If you work it this way , congratulations . Your Clarence Shepard Day Jr. of memorizing schoolyard game strategy were not for goose egg … or Cross .

Whew ! Detective work tax the mind . have us know how you did . And let us make love how we ’re doing ! We would eff to hear your feedback as we continue to shape the future of this series .
