The Candy Necklace is a popular feature as it lets you start levels with boosters. However, if you lose just ONE, then you have to restart. I found a cheat that will prevent this from happening if you're playing at King.com! Here's how:
When you lose your current level, don't replay it. Instead, refresh the page when it tells you to not give up.
After that, replay it. No win streak lost!
NOTE: This may not be the case for all King.com players. But just try your luck.
