For fans of all other kinds of logic puzzles

### Spinpossible - a mindbending 3x3 puzzle game

A few friends and I are working on a free puzzle game called Spinpossible (www.spinpossible.com). We're really excited to hear what sudoku players think of the game.

The rules are simple: you play by spinning groups of numbered tiles (see screenshots below), the goal being to arrange the tiles in order, 1 through 9, using the minimum number of spins.

The requirement to find solutions in the minimum number of moves makes the puzzles interesting because you can work toward the solution logically. I'll provide two examples:

1. In a 3 spin puzzle with one upside down tile, you know that there must be an odd number of spins that have odd area.
2. In the "Uniques" levels it is guaranteed that there is only one solution with the minimum number of spins. Therefore all consecutive spins must overlap because if they didn't then you could do the spins in either order, and thus there would be multiple solutions.

In addition, Spinpossible has special levels that prevent you from using certain types of operations, which requires you to learn how to solve puzzles in counter-intuitive ways.

It's our first game and we just made new versions for iPhone, Android and web. We’d love to get feedback and/or ideas for how to improve the game, suggestions for puzzles or game modes, comments on the art and sound, comments on difficulty and level progression, etc.

There are 4 modes of play:
1. Puzzle - we've designed more than 100 puzzles of increasing difficulty
2. Arcade - solve puzzles while racing against the clock
3. Random - play unlimited random puzzles of any difficulty
4. Multiplayer - challenge your friends or play rated quickmatches against other players

Here are links to each version. You don't need an account or anything to try it, but if you create one then you can sync your progress across all devices.

We also made a Sandbox feature for designing and sharing custom puzzles. Here's the a link to the sandbox

And here's more detailed instructions for using the sandbox
https://spinpossible.com/faq.pl#Sandbox

The short version of the instructions: To change the starting configuration of the board, enter the tile numbers in scan order (left to right and then down the rows). Put a minus sign before the number to turn it 180 degrees. For example here are 2 easy puzzles. (Hint, they can both be done in 3 moves)

a) 823456719 (1 and 8 are swapped)
b) 8234-56719 (1 and 8 are swapped and the 5 is upside down)

You can also use a # sign to make the remaining spaces blank, or to make gaps in the board. For example this string makes a 2x2 board with the 1, 2, 4 and 5:

12#45#

If you can create interesting puzzles using this please go ahead and share here!

The few people we've shown so far really like it. Please let us know what you think! We really welcome any suggestions or comments on how to improve the game and would otherwise like to know what elements are enjoyable. Any 5 star ratings/reviews would be super, but if you would rate it one star I'd appreciate it if you could post here first with why so that we can fix it asap. Thanks to everyone who checks us out!
