As much as I try to avoid describing all of the gameplay in reviews, sometimes it is unavoidable. With
Blokus World Tour, it is impossible; but the idea behind the game is really quite simple. Each player (there are four) has 24 blocks that, again, look like shapes you would typically find in a game of
Tetris. During each turn, players place one block on the board and earn points for the number of smaller blocks that make up the big, misshapen one. The object is to fit as many of your pieces on the board as you can, but with the restriction that only the corners of your own pieces can touch.
The simple corner restriction is what instantly takes a simple concept and turns it into a very complex game. Remember those awards I mentioned earlier? One of them was the 2003 Mensa Select award, which should give you a pretty good idea about the gameplay. There are a number of different strategies that you'll have to employ during each game, so if you're not that big into games where you have to think a lot, you won't like Blokus. The addition of three other players complicates your own strategy, requiring you to sometimes have to plan for every possible outcome - something that even Batman couldn't pull off. Okay, so maybe Batman could do it, but he'd need a lot of prep time.
Blokus is split into several play modes. The core mode is "World Tour," where you play against other players in tournaments set around the world. Each tournament has a different format that showcases different variations of the game. The more common type is 4-player, though there are also 2-player variations that are typically reserved for the Championship match.
A Quick Play match type is also available, which lets you play a quick game without the pressure of a tournament. Any of the game variations can be played in Quick Play, including 2- and 4-player multiplayer on one PC. The difficulty options are also expanded in this mode. My only complaint is the lack of online multiplayer, which really would have put the game over the top.
One of the more interesting modes is Challenge, which adds even more of a puzzle element. Each challenge places you in a situation where you need to perform a specific action. One may require you to win in a certain number of moves, while another gives you one move to keep everyone else from scoring. The challenges are varied and are sometimes more difficult that normal games, which makes them great from practice sessions since they teach you how to really get the most out of each turn.
