It would be the best game if you weren't cheated out of your reward for watching ads. From the beginning it wouldn't let me view the ads and gain rewards. now I'm lucky if I get through the ads and get rewarded. And now it seems I get halfway through the ad only to be denied the ones I need to continue further. And as gears that are denied are left on the playing field. This game has lots of bugs to work out. That's if the developers really care to fix these issues where most won't.

A game about gears that doesn't include torque or even gears of different sizes, what a let down. It's mostly a waiting game, speeding stuff up requires watching ads. Getting better units? ads. getting to use 1/3 of your hand during a turn? ads. getting to use the unique gears of a stage? ads. Not fun, and ramps the difficulty up after like 15 minutes to basically railroad you to either watch ads or pay money. Waste of your time, don't bother.

The game is fun and the only ads are for completely optional bonuses. The only negative aspects are piercing shots and multiple forms of currency. Piercing shots can kill multiple units including units that haven't even attacked yet, not to mention they can pierce through your castle walls(which is completely unrealistic), basically spawn camping. Spawn camping ruined many games. The currency problems are that you need different currency to upgrade at higher levels and you get way less of it.
