CrossNumber- puzzle with numbers for WP7, Silverlight, Android and Win8 metro game
Recently I decided to start with implementation of my first game which is going to be CrossNumber puzzle.
CrossNumbers is puzzle game which can be played from 7 year old children to mans in late year who like puzzle and math. The game is going to be for fun as well as for education propose which you can train your brain with math and problem solving. The game will be ported in Silverlight, WP7, Win8 Metro and Android.
Game contains originally designed problems which need to be solved in measured time, with penalty points for failed attempts. The game starts with simple cross number problems and rising its difficulties as you passing levels.
How to enter the number
Before you input the number you need to select cell by clicking or taping grayed (hidden) cell. Picture left shows selected cell which holds sum of 2 and 6. By clicking on the key you enter the correct value. If the value is incorrect the red rectangle will appear.
Type of Games
Currently there are two kind of games (curreently on two variant are implemented in alpha version):
· HDV Sum
· Sum to 11
HDV Sum stands for Horizontal, Vertical and Diagonal summation. This is classic CrossNumber puzzle. The simple problem is depicted below:
Suppose we have 4×4 grid (yellow area), with random numbers in cells. Red bottom and right row/column hold sum of the yellow cell in Horizontal, Vertical and Diagonal (right and left) direction .
If we want to sumthe first yellow column the sum is equal to 7. On the same way we are having sums for the next 2 columns and they are 6 and 8 respectively.
Now we are going to sum in horizontal direction. So, for the first, second and third row we have 4,6 and 13 respectively.
Now remain part is diagonal summation from the top-left to the right-bottom corner and left-bottom to the right-top. The values are 12 and 7.
This type of game will have 3 different grids: 2×2, 3×3 and 4×4 grids.
Sum to 11
The next type game is Sum to 11. This is game which is real ultimate brain puzzle and is not easy as you may think.
The picture below shows the rules for this game. This is math intensive game and represents real challenge for players.
On the upper part there is a 4 of 4by4 grids, which are indexed for constructing the equations bellow. You need to follow equation below in order to solve puzzle successfully. This game will also have some variants probably for summation of 11, 21, 33 and 55.
The game is already in alpha stage of Silverlight and WP7 platform, and it is accessed by very limited number of people. But very soon it will be opened to all who is interesting in game.
