Bonus flags are tiles introduced in Chip's Challenge 2. Collecting them rewards the player with additional points added to the total score after completing the level. The red, orange and yellow flags aware players 10, 100 or 1000 points respectively, while the blue flag doubles all collected bonuses.
Bonus flags behave as acting walls to all monsters, with three exceptions:
- Ghosts will pass through bonus flags without collecting or erasing them
- Rovers will collect bonus flags, but the player will receive no bonus
- Mirror Chip or Mirror Melinda will collect bonus flags, but the player will receive no bonus
Thieves will halve your current level bonus, so it is wise to collect bonus flags after stepping on any thieves, if possible.
