A numbers game.

This game gives you random numbers, that you have to distribute over three columns. The object of the game is to place as many tiles as possible. The game ends when all three columns are completely filled with seven tiles.

** Apparently there are other (iPhone) games with a similar name and concept. This is not one of those games and any similarities are a coincidence. **

** This is the paid version, with full functionality. There is also an ad-supported version with the same functionality, which is free, but contains ads. **

How to play (brief)
1. Get random number tile ranging from -6 to +6.
2. Put number in one of the three columns
3. Get next number tile and put it in a column
4. Clear a column by making the total of the combined numbers "0"
5. User powerups
6. Have fun

How to play (long)
This game gives you random numbers, that you have to distribute over three columns. The object of the game is to place as many tiles as possible. The game ends when all three columns are completely filled with seven tiles.

There are two kinds of tiles: round ones and square ones. The round ones hold "positive" numbers, from 1 to 6. The square ones hold "negative" numbers from -1 to -6. When you put multiple tiles in the same column, the numbers of the tiles add up (or substract) to form a total. When the total for a column equals 0, all tiles are removed from that column. Example: if you play a square -1 and a square -3 (making a total of -4) and then play a round 4, the total becomes 0 and the column is cleared. If you put seven tiles in the same column, without making a total of 0, the column is full and cannot be used again unless you clear it with a powerup.

Note on randomness: Each tile is determined randomly from the range of -6 to 6, with the following constraints: there is no "0" tile, and there will never be more than 4 positive (round) or negative (square) tiles in a row.

Scoring
Each tile placed in a column adds one point to your high score. Clearing a column by reaching 0 adds ten points. Aim for a massive high score.

Powerups
There are four powerups. A powerup is earned by clearing x amount of columns, listed in brackets below.
Power up 1 (5): "Reroll" gives you a new random number. Note: since this is random, it is possible for the new number to be exactly the same as the old number.
Power up 2 (10): "Get 8" gives you a posivie (round) tile with the value "8". This is helpful when you filled a column with a huge negative amount.
Power up 3 (15): "Get -8" gives you a negative (square) tile with the value "-8". This is helpful when you filled a column with a huge positive amount.
Power up 4 (25): "Clear All" will clear all tiles from all three columns, so you can start over fresh. Your score is not affected.

Game types
Four game types exist, each with their own twist:
Normal game: the basic form. Easiest to play.
Extreme game: same as Normal, but totals for columns are not shown. You will have to calculate the totals yourself.
Insane: totals for columns are not shown. Once a tile is put in a column, you will only see whether it is a positive or negative tile. This means you have to remember all the tiles you played. Or just guess.
Timed: same as Normal, but with a 60 second timer. Try to stay alive and get as many points in one minute. The game ends after 60 seconds or when you fill all columns, whichever comes first.

Bugs and troubleshooting
On some devices the game may feel laggy when the game sound is on. Turn off the sound for a smoother experience.

Recently changed in this version

*** Update by end of August 2014 or old version may crash ***

Scoreloop leaderboard option has been removed as that service will end soon. I want to replace it with another service in a future version. Internet & phone state permissions are no longer required.

Also, I realize I need to better accommodate larger secreens, so that will also be something for a future version. In the meantime, I hope you will still enjoy the game.
