From Emanuele Feronato: "With new version of Phaser being released quite often, it’s important to keep games updated and when you update a game it’s always the right time to add some new features.
This is what I am doing to my SameGame prototype built with Phaser 3 and the pure JavaScript SameGame class which now has a new configuration variable: by setting fallingDown property to false, blocks will fill empty spaces from by flying to the top rather than falling to the bottom."
