The Bot Squad is half a puzzle game, half a black hole for your money, it's gameplay mechanics well thought in order to minimize your enjoyment of the game if you're not ready to annoy someone on facebook or to give them cash. It's something that looks like a puzzle game but quickly turns into something else, a primordial paste of energy timers, premium currencies, best values and robots.
The first few levels are okay, you have robots to either attack or defend and you have to use them properly in order to get somewhere - or to prevent enemies from getting somewhere. You also have to collect three stars per level - and it doesn't take very long before just playing the right moves isn't enough, because you have to level-up your towers and your robots in order to match the enemy challenge. Leveling-up costs time and resources, which you mostly get for collecting stars. So it's not really a puzzle game, because your actions are taken in consideration AFTER the way this game was balanced, which is to say to take your money.
There is a huge world map where you go from stage to stage - with annoying loading screens in-between everything - and you change from attack to defense, you unlock new robots and towers, you get to reward squares where the game gives you some pity energy charges so you're not stopped playing after the first five minutes, and you go on like that for a while, until you can't. Until the game says "This level requires level 2 towers, would you like to upgrade, alright, it's going to take a few hours, or you can give us some premium currency, wink wink." and you can't really win without the recommended level. You also can complete daily quests and get daily rewards. You know, quests like spamming people on facebook.
The towers and bots are 'interesting', they have various abilities, they punch, grab, throw, shoot. Some levels have you place them and then the level goes, some levels let you place them during the advance of your enemies. When you have robots, you move them by swiping their paths. I really wish there was a way to fast-forward the game because everything moves really slow. You can also use power-ups which cost premium currency, like a blast that stuns enemy robots and towers, allowing you to 'out-puzzle' the puzzles, with money.
This game could have been a real game if you paid 20$ for it and then just played through all of the puzzles without having to think about robot and tower level. Make it a straight puzzle game or otherwise what you have is this money-grabbing mess with too many systems and not enough playtime.
