I’ve addressed this question before, but with so many new players, it’s worth an update to include the changes (or, rather, the return to the way things used to be) that came with Whacking Day update.

Up until you reach level 27, your XP bar is blue and fills up normally. But when you get to level 28, a little gift box appears at the end of the XP bar indicating that you won’t be moving to level 29 (because it won’t be ready until mid-May at the earliest). Instead, you’ll be hitting a bonus level:

Once you reach the end of level 28, a popup appears giving you a choice of 1, 2 or 3 donuts:

This is what you’ll see if you’re lucky enough to win 3 donuts on your first pick:

If you don’t win 3 donuts the first time, you can pay $50,000 for a second chance:

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 29 is released, you’ll automatically level up and your blue XP bar will appear again, no matter how full your pink XO 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 28 – and that’s because, as at the date of this post, there is no level 29.

3. Your XP maximum changes. For the first time through the bonus round you’re heading for a maximum of 148,896 XP. The second time through, the maximum will be 178,675 – and it will increase by 20% each time you go through a complete bonus level and get the free donuts. This is a change from March, when the XP maximum each time you passed through a bonus level remained at 120,000, but this is exactly how it worked when the bonus levels were introduced at the end of January.
