• Plushed Gold Fever is a colorful running game that's free this weekend.

• Tiny Heroes, which we picked as a Daily App earlier this week, is staying on sale for just 99 cents.

• The 2D RTS Swords and Soldiers is on sale for a buck as well.

• Gameloft is having a big sale, with many titles down to just a buck, including NOVA, Dungeon Hunter 2, Splinter Cell Conviction, and Rayman 2.

• The great Legendary Wars is free for the weekend.

• The oddly named Radballs is free as well.

• Sid Meier's Pirates on iPad is only $1.99.
