A big bunch o' arcade games have been assembled for this week's Mobile Monday. It was actually really easy to gather them, too. All I had to do was put out a bit of arcade bait and they came a-runnin'...

Wild West Pinball - I'm as much a pinball fan as I am a connoisseur of Somalian sorghum. Which is to say, I'm not. But I had a pinball itch for some strange reason, my iPod was in my hands, so I went digging. I found Wild West Pinball, a free, single-table pinball game that goes to great lengths to preserve the old school pinball feel, which I can appreciate. It's got bank robberies, an Indian village, a wanted criminal, railroad tracks and more. Nice setting, good pinball action, and you can't beat the price. Oh, and be sure to watch the title screen for a few seconds for a 3D tour of the table.

Knights Onrush - From prolific iPhone game publisher Chillingo comes a rather handsome castle defense game in the tradition of Defend Your Castle. Knights, bomb toters, and other baddies rush the fortress to the side of the screen. Using your almighty finger of almightiness, fling them to the sky to protect your beautiful pile of stones. Buy upgrades to improve both your offensive and defensive capabilities in-between rounds. Things get real hectic and real wacky after a few levels. A free Knights Onrush Lite is also available.

MUST. EAT. BIRDS. - Gotta love a game with that straightforward of an objective. Also gotta love a game with a character called a nomster. Fire nomsters from the makeshift slingshot by dragging and releasing the rubber band. Your goal is to not eat the birds— just kidding! Chomp away at those fluttering little things, the more the nombetter. Crash a couple of nomsters together to make a big nomster. You know you want to.

Star Trigon - Based on the original Namco arcade game from 2002, Star Trigon is all about rescuing uchujin who are adrift in space. Your character circles small planetoids either clockwise or counter-clockwise. Tap the screen to hop from object to object, leaving a trail in your wake. Fence the uchujin in with a trigon and your work is done! The tutorial is short and painfully slow (just let me play already!!), but otherwise the game's a great little time waster. A free Star Trigon Lite is also available.
