There are only 23 swirls on the board. The player is required to get at least 7 more from dispensers. The problem is, the dispensers are above the popcorn tiles and there is only one swirl coming out each move.
This level is much harder on HTML5, since swirls do not respawn in the next move after removing some.
Other required blockers are provided and must be totally removed. Luckily, with four colours, removing the popcorn is not too hard.
