Big games, small packages. Well, iPhone apps don't really have packages, but you get my point. Without losing their pick-up-and-play appeal, this week's games stuff a lot of content into your hands, offering weeks upon weeks of casual entertainment.

Fishtropolis - From the creators of the unbelievably appealing Textropolis comes another word game where you spell words from other words! This time, instead of picking apart city names, you're working with fish. That's right, fish. How many words can you spell using the letters W, H, I, T, E, C, A, R, P? Hope it's a lot, because you'll need to cull dozens upon dozens of words out of each name before you can move on to the next stage. Challenging, but boy will you have a great time.

BLOCKOBAN - A slick puzzle game where your goal is to slide colored blocks over colored points on the screen. Most blocks keep sliding until they hit a wall, creating that all-too-familiar Sokoban scenario, but BLOCKOBAN mixes things up with several different objects, including linked blocks, sticky tiles, and — wait for it — circular blocks! Excellent design with captivating and challenging gameplay through and through. Best of all, if the included 100 levels aren't enough, you can upgrade the game for a whopping 800 stages. Also be sure to check out the original browser version of Blockoban.

Red Conquest! - A decidedly non-casual real-time strategy game from the creator of Blue Attack!. Red Conquest packs a full-on RTS game into a small package, including just about everything its tactics-oriented PC brothers would possess. Apart from the story that ties together the studio's previous games, your goal is to stay alive and defeat your opponent. There are only a few unit types to worry about (whew), such as harvesters who collect resources, cruisers to do the fighting, and carriers to haul stuff around. The learning curve is intense (and the tutorial isn't very helpful), but I promise you, if you stick with it, Red Conquest rewards you with an incredibly satisfying strategy game on the go. Plus, online multiplayer is promised in a future update!
