Here is a great new game that is free to play, available on both iOS and Android, and does not have an obnoxious in-app purchase model: Hit the Light, a new brick breaker puzzle game.
Each level in the game is a carefully crafted picture made entirely out of neon lights. Your job is to demolish them using different tools, each with their own unique characteristics: a bomb breaks everything within the parameter of the explosion, a ninja star slashes through everything in its way and bounces off the level's walls, while metal balls ricochet against the neon objects. Unlike a traditional pinball/flipper type of game here, you don't have a paddle here and the balls don't come back, but instead you have a limited amount of shots with each tool.
I have played through the first dozen levels and what hooks you up is that so satisfying sound of breaking glass. The game is definitely not too challenging, but not too easy too, so it feels enjoyable to play.
Hit the Light is free to play with in-app purchases, but you can easily skip them altogether and they are not terribly intrusive. Of course, if you like the game and want to support the developer, we strongly suggest you actually spend the $3 to do that. You also have another type of in-app purchases, diamonds, which are the game's currency that you can spend on buying all sorts of fancy guns. As you play the game, you will be able to try those guns out for free, but the other attack weapons are also a lot of fun.
At the end of the day, Hit the Light is a fun little game that does not overwhelm you with ads and that gives you your quick gaming dopamine fix that you will enjoy.
