Gameplay is relatively simple: you have to push all the bombs you find scattered throughout the levels and make them explode. This will create holes in the wooden tiles so you can access the square coins that let you to move on to the next level.
The rules, basically, are that your princess can only jump to the next-highest tile above her, so she has to detonate the bombs from above (where the fuse is sticking out), and she can only move the bombs in a straight line. Even with just these basic rules, the game can get pretty tough pretty quick.
In order to put your ingenuity to the test, there are 10 different levels to play. You'll have to do much more than detonate the first bomb you come across, so much so that you might get stuck for a while on some levels.
Princess Chardonnay in Bomb Kingdom is a very fun puzzle game that, despite being pretty short (it only has 10 levels), still offers an entertaining and ingenious gameplay that will put any player's mind to the test.
