Talking about Bejeweled game, Game development, HTML5, Javascript and Phaser.
The Bejeweled prototype made with Phaser gets a new update with a new feature. Last time I showed you how to suggest moves and now it’s time to reward matches of four jewels by removing the entire row or column, and to reward match of five jewels by removing all jewels with the same color as matched jewels. Have a look and try to do some four or five jewels long matches. Do you want to see how you can do this? Have a look at the source code, I highlighted the lines of code added since the previous version.
