Bloontona 500

"Gain entry to 500 races"

- BTD6 achievement description

 is an achievement in BTD6. It can be achieved by playing races, and completing it grants 250.

Tips

 * The same race can be entered more than once to progress on this achievement.
 * A race "entry" simply means starting the race, and the player does not need to finish the race to count towards the achievement.
 * A race lasts for almost four whole days, specifically between Friday 8:00pm NZST and Tuesday 3:30pm NZST, and a free entry is given every three hours.
 * Have the Grand Prix Spree MK active, so that discounts for extra race entries can be possible, saving Monkey Money in the long run.
 * Buying a Race Pass could be useful for grinding up the 500 race entries, but requires an in-app purchase to unlock a Race Pass, and with a minimum price of $2.99 USD (?) for 4 Race Passes, it's generally less valuable than spending app money elsewhere. Still not the worst option if trying to earn this achievement is the current goal.
 * There is a free Race Pass earned from the Treasure Chest on Day 50 (and every 50 days after), benefiting players depending on how many days they have stocked up.
