I’ve addressed this question before, but there are a few questions on this in the comments, so I thought it was time for a repost.
Up until you reach level 30, your XP bar is blue and fills up normally. But when you get to level 30, a little gift box appears at the end of the XP bar indicating that you won’t be moving to level 31 (because it hasn’t been released yet). Instead, you’ll be hitting a bonus level.
Once you reach the end of level 30, a popup appears giving you a choice of 1, 2 or 3 donuts:
If you won 1 donut the first time, paid for a second chance and won 2, then you keep the 2 donuts you won the second time (they’re not accumulated with your first win) if you stop there. If you won 2 donuts the first time, but only picked up 1 donut the second time, then you get to keep the highest number. And if you’re not happy with your second pick, you can pay another $50,000 for a third and final pick, where you’ll certainly end up with 3 donuts. But the maximum number of donuts you can win at any bonus level is 3, no matter how much money you pay. And that’s because all you’re really paying for is a second and third shot at the 3 donuts that you may well have won first time round had luck been with you.
Three more things happen:
1. Your XP bar turns pink. Behind the scenes, your blue XP bar is full and waiting for the next level. When level 31 is released, you’ll automatically level up and your blue XP bar will appear again, no matter how full your pink XP bar is at the time. In the meantime, you’re playing the bonus game, which means that you’re filling up a completely different XP bar.
2. The game continues to show you as being at level 30 – and that’s because, as at the date of this post, there is no level 31.
3. Your XP maximum changes. It will also increase by 20% each time you pass through a bonus level.
Remember, that second or third chance costs you – but it’s also currently the only way you can use game dollars to buy donuts.
