Most people know Bram Cohen as the founder of Bit Torrent. To me, he's another puzzle friend who regularly attends the International Puzzle Party every summer. And it's fast approaching!

He created this Sudoku puzzle and describes it thusly:

My first attempt at making a sudoku. This one might be obnoxiously hard in a bad way.


I have not had a chance to try it. But I've always liked squiggly sudokus.

Transmission is an education puzzle app that combines a little topology with various technological gadgets. Essentially, you must draw links between certain devices: transmitters, receivers, transceivers, antennae. You'll learn about looping, signal types, signal swappers, signal blocks, base stations, and repeaters.

There are 69 levels, and I've solved 50 levels. I actually played this game about 2 months ago. And I must confess that I've already forgotten the abilities for each machine. Yeah I didn't retain much. But I do remember thinking the game was kind of fun.

Case Ertel is the author of Delta: It's All About 4.  Seems like another version of Threes!  But it' not.
The idea is to fill the screen with 4's.  You can combine adjacent numbers. Or you can split a number.

      

This game goes pretty fast.  A few levels are pretty tricky, like #81 which I needed extra moves.   Unfortunately, there is no way to go back and select any previously done level. At the moment, I'm stuck on 110. Which I think is impossible.


Each grid size is 2x4. Which is a shame because after a while the puzzles become too repetitive.  Maybe the grid size changes, but there's no way for me to find out.....unless I keep doing them.


Here's another thing that bugs me: when I select next puzzle, why do I have to then click 'play'?


Some things that work well: good graphics. Good concept.


Overall - play it only to see how fast you can solve them.  If you manage to do even 300 of the 1000, please contact me and explain if the game gets any better.

Nikolaus Banjo recently contacted me about his new game Jumbl. The idea is to swap letters to create words.  Suppose you tap on an E. All the E's will be selected and if you then tap I, all the E's will swap with all the I's. 
Jumble is okay, but as you Loyal Blog Followers know, I'm not much into word puzzles.

Not too long ago I played Cube Escape: Seasons. Pretty terrific. The same folks made a much shorter game called Cube Escape: The Lake.  And now, there's Cube Escape: Arles. It's also pretty short, I solved it in about 1 hour.

Look at the image above: do you really need me to tell you what it's all about?

I liked Cube Escape: Arles - it's easy enough and has one very interesting operation that I won't describe.

These guys at the Cube Escape franchise have got a good thing going and I'm going to play anything that they release.

Colorazy is a nifty puzzle app game where the objective is to create a single path from the one circle to the other. The path must traverse through every square cell.


Look at the first image: see the white lines? They indicate that there is no matching color between the adjacent cells. You must tap on the individual squares to rotate them.



There are 120 free levels and I've done all but 4 of them; they can get quite challenging. The first 80 are relatively easy. But it's fun to see how fast you can do them.




I'm thankful: look, this game kept me entertained for at least 2 hours. To show my appreciation, I spent $2.99 for the premium upgrade: no ads and two sets of new levels.  On one of them, the white walls are never shown.


Colorazy is in the running for a PAGY Nomination. (Check back here on December 30th.)

Jordan Naftolin is the author of Pegs 'N Holes. The objective is to transfer the pegs into the holes, obviously.  The grid sizes range from 4x4 to 9x9.
I've solved a few levels at each grid size.  They go pretty fast.  On the 9x9 boards, my fastest time is 162 seconds.
Pegs 'N Holes has great graphics. It's not terribly hard, but it is fun. I highly recommend this for young puzzlers.
