From mobile puzzle maestro Kris Pixton, SpellPix is a new take on the path-drawing logic puzzle seen in games like HUEBRIX or Conceptis' Link-a-Pix. The idea is to connect the marked letters to an identically marked letter somewhere else on the grid. The path can snake around as much as it likes, but it has to be unbroken. In SpellPix, each grid square has a letter, so with every pair of letters you match up, you'll also spell a word.

On a quest for pieces of a map, you'll travel from Rapa Nui to London to Monte Carlo, solving a series of themed logic games with difficulty levels ranging from "no duh" to "...HELP!!!".

All of this happens on a timer, so you've got to be smart, you've got to be fast, and it wouldn't hurt to have a positronic brain, either.

But by combining these things, we can come up with other things to combine into still other things with an end result of 235 things!

One area where organic intelligence beats artificial intelligence every time is finding abstract relationships between two or more things.

Your job is to pair them up, tapping a word on the left and matching it to a word on the right. You can't move on until everything is correctly paired up, so you have to think both inside the box and outside of it at the same time!

In the beginning, there was nothing. Then, some things were created by an all-benevolent superbeing-type god. A not-so-benevolent deity also has a job to do, though, and once the world exists, his task is to cause a little mayhem. The original Doodle God, both the iPhone version and the browser game, focused on creating the universe by mixing basic elements one after the other. Doodle Devil, on the other hand, is about crafting the darker side of life, blending rudimentary concepts together to create chaos.
