The concept of gameplay is pretty simple. You have a set of rules, and from there you need to strategically try and play the game. You use your left and right mouse button to play a "P" or an "O". The object of the game is to get as many "pop"'s as possible, and of course, giving as few away. A pop is the letters P O P in a line vertically, horizontally or diagonally. The player who has the most pop's at the end of the game, wins.
Our Review: This game fits into the same genre as minesweeper - ie small windows based thinking games. It bears similarities to the legendary time filler squares - you know the one where you and a friend take turns drawing a line on a grid of dots, with the object being to connect the most squares? This time you take turns placing either a 'P' or and 'O' inside in a grid. If you spell POP, you get another turn.
The computer has got this game sussed, and kicked my sorry hide on easy level in my first ever attempt, so perhaps net-play is a better option.
