Watch out! There are
**MONSTERS**
behind these doors!

**Dungeon Doors** is a challenging puzzle game with
strong math and logic themes, in the vein of *Sudoku*,
*Kakuro*, *Magic Squares*, and the like.

In *Dungeon Doors*, you lead a team of adventurers into
the dungeon, and fight the monsters behind the dungeon doors
by using teamwork and the special abilities of each character.

Each monster has a number, and your job is to line up your Sifteo cubes so that your team members make an expression that is equal to the number on the monster, in the gray area at the bottom of each cube. Get the number right, and you vanquish the monster!

Here's an example. The monster has a value of **8**.

The **warrior** can have a value of **5, 10, 15, or 20**.
His operator is *addition*.

The **archer** can have a value of **7, 14, 21, or 28**.
His operator is *subtraction*.

The **mage** can have a value of **1, 2, 3, or 4**.
His operator is *multiplication*.

Lining up the adventurers in a line lets you make an expression. The
operator of an adventurer is used on the adventurers to his or her right. For
example, putting the warrior first and then the archer would combine their
numbers with *addition*. Putting the archer first and then the
warrior would combine their numbers with *subtraction*.

Here is a solution that defeats the monster:

Five plus seven minus four equals eight! Can you find more solutions?

Here's some video of the game in action:

As usual, programmer art alert!

**So where do we go from here?**

This game is an entrant in the Sifteo Cubes Experimental Gameplay Competition.

Our hope is to get some non-programmer-art artwork into the game to make it look halfway decent, and flesh out the game with some real dungeon delving antics, new monsters, and new mechanics.

Even better, we want to rope some teachers into testing this game with kids in math classrooms, and perhaps writing some lesson plans to go along with it. Unlike a lot of the "drill and kill" math games out there, which would just ask things like "what is six plus four?", this game rewards strategic and creative math thinking, and encourages collaborative play with mathematical concepts, breaking down barriers and apprehensions about math for kids and adults of all ages.

**Want to try it out?**

If you have some Sifteo cubes, and you're enrolled in the Sifteo developer program, you can download and try the game yourself!

Please note that this is **far from finished
software**. Unlike our other Sifteo game, this one
is barely a prototype, and doesn't have any real tutorial
or gameplay options. We hope you enjoy it just the same.
