Tetris meets Sudoku in this addictive puzzler.

How to Play:

Play in basic (try and make a group equaling 9), timed (drop tiles under pressure) or arcade (the quality of your play leads to power-ups). Drop tiles into the grid. Try to make adjacent tiles (columns or rows) add up to the required value. When you do the tiles in that group change colour, until eventually some will turn red. Make a group with a red tile and it will explode, causing the tiles above to drop down, leading to combos and big points!
