Here is a short YouTube video demo of how we play BonusBall:
The aim of the game is to prevent the board from filling up by
strategically aligning 5 objects of one color into a vertical, horizontal
or diagonal line which will instantly disappear. You can only move
one ball at a time by clicking on it and then clicking on the cell
where you want it to be moved. This is how you build the lines:
Moving balls can block each others road. With every turn you may
move only one piece and only if there is a clear path to its destination.
Three more pieces appear on the playfield randomly after each move,
unless you removed a line. You receive points for every removed
line. Aligning more than five pieces gives you even more points
but it is risky as you might not be able to complete the row if
a new ball appears in an unsuitable place.
Remember that you get more points for:
Removing more than 5 balls at a time
Playing on a harder level (you can change game level in Game
menu - Settings...)
The game ends when the playing area is filled and no more moves
are possible.
