The Offering is a ball toss game. Players throw 25 balls into a grid of color coded square cups, the higher-value cups being near the center of the grid. A UFO flies above the cups, launching away balls that intersect with its search beam.
If the player reaches 1,500 points or higher, bonus mode begins. Bonus mode causes all the cups to change color to a rainbow gradient; despite this, the point values for all the holes remain the same. Instead, reaching bonus mode increases the ticket payout to about half of the ending score.
If you can find the exact spot to throw balls and consistently land them in the center gold cup without moving your mouse, you can earn over 2,000 tickets per game, making The Offering one of the most efficient games for grinding tickets.
The lore for The Offering, as shown on the Help menu, reads, "When interlopers from the cosmos come bearing gifts, you know to reject their offering. ...Aim for the center cup to most defy the offering."
Prior to Arcade phase 1.5, the score holes were small cups instead, and there was no flying UFO.
