Nevertheless, Caisses offers a fun way to test your brain during a break from your usual routine. The graphics aren't the best ever and because this version is ported from a mobile phone version, the game window is quite small. It gets pretty tough as you progress through the 500 levels, so it would've been nice to see some kind of hints feature, but the challenge of getting your head around the hundreds of puzzles is enough to keep you coming back for more. You can play it on mobile devices like Apple iPhones, Google Android powered cell phones from manufactures like Samsung. This game is rendered in mobile-friendly HTML5, so it offers cross-device gameplay. Build valid equations by moving the number tiles into the correct positions. For instance, you can choose to play as Pac-Man, Zangeif, a nurse, or even the Linux penguin, and the objects you push change accordingly. Sokomath is an Algebra equation building game which was inspired by Sokoban. Not only can you choose from a bevy of cool backgrounds, but there are loads of game themes to choose from too. The best thing about Caisses is the fact that you can customise the game to the n-th degree. As a result, the gameplay is very addictive, but certainly not very original. You can only push the boxes in a straight line, and you can't push more than one box at a time. Your basic aim is the same old story - you're a warehouseman who must shuffle parcels around.
