R.T.3 SEARCH coming soon

I’m excited to announce that early next year, the first ever √3 Riddle Search will take place!

Because √3 ≈ 1.73, the search will take place on January 73rd, (counting February 1st as January 32nd, February 2nd as January 33rd, and so on.)

Coin Puzzle

Hey there, I’m 23 🙂

There have been a lot of changes since I turned 22. I both started and stopped working at Google since then! Here’s a puzzle themed around 23 and change:

Take 23 cents arranged in the 2 above, and change them into the 3 (pretend all pennies are indistinguishable, and all nickels are indistinguishable.)

You can make 5 moves, and each move consists of picking a contiguous group with 1 nickel and 2 pennies, and moving that group, without rotation, to a new spot.

P.I.HUNT 6 in a month!

Hey there,

Is it Valentine’s Day already? We’re getting EXTRA CLOSE TO NEW PI. There’s only a month until the 6th P.I. Hunt!
Solve the anagram to learn what you should do to prepare:

EXTRA CLOSE TO NEW PI = ????? ????????????

PUZZLE 151 – LIQUID MEASUREMENT 2

Hi! I’m 22 now!

Last year I posted a puzzle about measuring alcohol, and each even year has been a harder version of the same type as the odd year, so be warned for a very difficult liquid and cup puzzle!

I’ve graduated college now, and moved to a job, which means I can finally afford two cups. You’re now given 2 cups, both perfect cubes made of glass of negligible thickness with a volume of 22 units of alcohol. That’s way too much for me! Your goal is to measure exactly 1 unit for me.

You’re also supplied with a tap, that acts as an infinite source. Assume that the cups are see through, so you can fill one cup to the height of the other. Also if you rotate a cube to some angle, you are able to hold it still at that angle if you want. You don’t have a marker and can’t make any markings on the cups.

Good luck! Next time will be less mathy probably, but you’ll have to wait another year for it.

 

Puzzle 150 – Liquid Measurement

I turn 21 today!

If you haven’t seen before, I post an age-themed puzzle each year (Here’s last years). 21 is drinking age (in US), so I have a drinking related puzzle for you.

Normally in these sorts of puzzles, you have an unlimited amount of liquid, and 2 or 3 cups, but like all college students, I’m too frugal to give you all that! In this puzzle, there’s only 1 cup.

The cup is a cube, measuring 10 units in width, length, and height, and which also has a vertical dividing wall that goes halfway up cutting it in half. I’ve attached a diagram to make it more clear, along with a front and top view.

You are given the cup and a straw, and the cup begins filled to the brim with beer. Besides the beer that comes in the cup, you aren’t given any extra (or any source to keep beer you’ve poured out.) Your goal is to drink exactly 21 cubed units of beer.
