RoboZZle Droid

Over 1024 levels from very easy 1 minute ones to extremely hard, which could take hours to solve.
RoboZZle is a cool programming puzzle game invented by Igor Ostrovsky. Your program will control a robot to collect all items from 2D tri-colored field. You can move, turn, repaint cells and call very short (in most cases) functions.

So, you need three instruments to solve robozzles: your mind, your hands, and recursion!

First time player, I recommend you to pass site-based tutorial at http://RoboZZle.com (which can be done from Windows PC only), since help screen currently contains only textual description.

NOTE: This game is known to crash on start on some Lenovo devices!NOTE: The game has a known bug, that prevents it from running on devices, where system interface is set to Turkish.NOTE: This is the 3rd prerelease of an offline client to http://RoboZZle.com website and the first version that can synchronize your solutions with RoboZZle.com

I just realized Ive never rated this game and this is actually the best game for Android Ive ever played. My lecturer on first year of CS recommended this game to us and I spent the whole term playing it like crazy lol. It was like 5 or 6 years ago now I do programming for a living and I see how being good in this can help you in being a good programmer. It's essential.

Needs a colourblind mode. I can't see the difference between the shades of red and green used so most of the game is impossible for me.

As soon as I started it it gave me a bunch of achievements, said my device was incompatible with no further explanation, and allowed me to play only two levels.

Great game just wish there were hints on how to complete stages. So now if you're stuck, then you're stuck for good.

As a non programmer, this game is sperb I struggle each one and it is never obvious

A distillation of the essence of programming, great for developers and aspiring developers!

How do I even play this? There is no proper instruction!

An amazing and simple idea. Really fun for people with coding knowledge. Just a quick suggestion: there should be a fast forward button as well (other than the regular "play"), so you can swiftly go over the levels you solved but just have to wait a long time for the run to be over.

I've been playing this game for more than I dare to say, but over 5 years. It's been the only game app on my phone for quite some time, and this is all one needs. The thrill, the aventure, the suspens, it has it all. Sure, the interface is crappy, but eh. (Suggestions include : a slider for speed, inserting instructions, stack display, forum integration,...)

When I try to play the game it says " can't modify while running ".. Please help

It helps us think logically :)

Simple yet very addictive. This is a puzzle games that involves some simple programming. And it's one of the better mobile games I've seen.

Is there a way to execute step by step?

Amazing game for programmers...

Thank you for such good game. The sad news that i can't find any button on my Asus ZenFone5. So I couldn't made any option change, donate, synchronize. Please, fix it. UPD: on newest Android versions there are no hardware menu button. Only virtual menu button

From what I've seen of it so far, this game has interesting puzzles, and doesnt suffer from the interfface problems that plague so many of its mobile colleagues. The only trouble is, I can only access 6 of the puzzles. What's the deal with that? EDIT: Ah, I see, thank you! Altho, you should probably give it its own touch screen buttons

First you have to figure out a path to traverse the puzzles. Sometimes this is obvious; other times it's not. After that, you then try to write the program to walk the path. This ranges from trivial to very tricky. Oddly, this game promotes bad programming practices: using recursion when a loop suffices, and not ending the program nicely (most solutions leave junk on the stack).

Fun, hard logic puzzler. Highly recommended for programmers/computer science students.

All is nice except for synchronising new levels..it takes a lot of time and even not sure that they will come or not..! Plz do somthing for this..!

Pau. B. Sep 24, 2014     

Loved this game on the web, love it on mobile. I wish there was a way to change the execution speed: I'd like to test my programs faster. EDIT: Ah there's a way (see answer). Cool!

Hard puzzle game, highly recommended for computer programmers!

A. G. u. Aug 13, 2014     

One of the best game I know

abi. b. Jan 19, 2014     

The game is fun and challenging, but the Android UI isn't good, it's difficult to stop at specific points to figure out errors in the Algorithm. It would've been nice if it had user logins so I could same my levels between devices

The lack of tutorial to help learn new coding structure is limiting the potential of this game. Besides that it's as Great as it is simple.

My 7 year old is having lot of fun with this game, and she's learning some programming concepts. She needs help, but it's a great way to teach simple programming.
