So annoying. What's the point of it? Are they saying we should try to make moves trying to get to it? As if we don't know that? And I play on my laptop where there is no setting to turn off hints.
When I see the flashing booster I can double tap it and the booster does what’s needed without having to match it. It does count as a move just by itself, but is useful if it’s not near something to be matched.
As mentioned in the thread, have you tried double tapping the special candies to see if they get activated? There's a new test in the game where you can use the candies by double tapping them.
