Quick Tips, XBLA

Soltrio: Grandfather Clock is the easiest game to earn the 100 games won and 1000 games won achievements (use auto-play and fastest animation options). You will always win at the Memory game if you're trying to get through Voyage Mode. Klondike (not easy Klondike) can be beaten, eventually, in a minute with auto-play on. When going for completing achievements, don't worry about your score!

Band of Bugs: Wet Bug Smell, pushing the enemy off the map, making 50 ice tiles, using 25 skills, and a couple others can be achieved by setting up the proper situation in edit-mode and then running that map in Skirmish mode.

Pac Man CE: To nab the Crown, as well as all other "fruit" achievements, play a 10-minute game and focus on completing one half of the board over and over. On the modes that are "feast and famine" with the power pellets, work on one half of the board and save the pellets on the other side for emergencies. If the other side is running low, get to a layout with a lot power pellets on the other side, then work on it until you have to switch again.

Luxor 2: To earn the 100% accuracy achievement, play Pharoah's Challenge where you shoot only daggers. Then carefully place all shots to cause large matches.

WHAT THE HELL DOES "3 for 50G" MEAN? The latest dashboard update will add together all achievements if you simultaneously get 3 or more.

Want to jump quickly to the game you played 3 days ago? When you enter the XBLA "My Titles" list, there is a special filter, by pressing Y, that will sort your games from most recently played to least recently played. That helps a lot if you don't want to play the last game played, but the one before it.

And the most practical tip, if you keep your Microsoft points low, you'll buy less XBLA games.

One 400 point game is worth it if you play more than 10 games! Coin-op games cost fifty cents (US$) or more, so 10 games in an Arcade is 5 bucks!

One 800 point game is therefore a good deal if you play 20 times or more (including continues!).

EDIT:  FIXED THE BAD MATH
