Who knew that the Four Color Theorem would make for such a nice simple idea puzzle game? OneFifth's Flood Fill is a fun and colorful way to fill up a coffee break, even if its 20 levels are over way too quickly. But hey, the background music is catchy.

Cute game. Gold-starred every level, although those stars look more bronze than gold.

Talk about a blast from the past.. I played this game on Kong when it came out in 2009.

It doesn't lose its appeal of trying to get gold star on every level. It's a good little game. Not too frustrating.

1. The image text for the Flood Fill picture says "ir/rational Redux." (Probably a copy/paste error.)

2. And Tricky, I believe you mean "a MINIMUM of four colors are required to color the regions of the map so that no two adjacent regions have the same color," not maximum.

And as someone who dropped my major in mathematics when the going got rough, all I can do with regard to the Four Color Theorem is to quote Lurch from the Addams Family: *low groan*

The more I think on it, the more I see that either would work, depending on the particular phrasing used and the particular puzzle presented.

The Four Color Theorem explicitly deals with such maps that are trivially solvable with more than four colors, but challenges the individual to ... Okay, Tricky. You're right. It's maximum.

(Can I plead illness here? Addlepated and easily confused? 'Cause I am home from work with a fever.)

Nice little game, it just went by so quick. Even going back to redo the levels I didn't get the gold star the first time didn't take very long.

That was fun and relaxing. Just the right difficulty for me.

I loved this game. I actually managed to understand it and win all the levels, plus it's relaxing. 5/5.

Awesome game, it just soooooo needs to be longer. :)

I was in the mood for a good relaxing puzzle game.

This filled that void.

It is a little annoying that it just flips off to the next level when you have completed regardless of whether you want to fiddle to get the gold star or not.

I know you can go back but it is just a little irritating.

Fun other than that though

I love this game. I just got all the gold stars, and I want more levels. Does anyone have any "if you like this game, you will also like..." recommendations?

While not exact in gameplay, these games have a same-y feel as far as play style goes:

It's always a fun adventure to go spelunking through the JIG archives, also; you never know, you might discover your new favorite game there!

Edit: Almost forgot to point out, try following the tags at the top of the article, too. For example: the color tag! ;-)

Excellent relaxing game that needs more levels! However, I'm with yaddab regarding auto-flipping to the next level...

really great game. way way way way way too short.

five stars for expoexponentially more levels!!

Hooray for math-related puzzles. A friend of mine had a game like this (or this game precisely) on his iPhone once. I played it all the time. That and Trainyard.

Anyway, the four color theorem is awesome, and also true, which means if I absolutely couldn't figure out how to do a map with just 3 colors, I could add a fourth and it would just work (as long as I did it carefully).

Personal method of getting the harder puzzles:

At every "T" or "Y" intersection there must necessarily be three different colors. Start filling stuff in with a single region that is adjacent to such an intersection, then chain together these intersections with the logical premise, "if there's these two colors already there, use the other one for the other side of the T/Y".

When you run out of Ts and Ys to chain, randomly pick which colors to put around an "X" intersection (or any intersection with more than three incident regions) and then go back to using logic to determine what to fill in. You should get it eventually.

My only disappointment was the lack of a "clear" button to clear all the colorings from the map (without going back to the previous puzzle and going forward again).
