They work on the same core principle as Battle Beastformers in that it's essentially rock-paper-scissors, but more complex in the following ways:
+ Whereas Battle Beasts' "weapon" is pre-determined by their rub sign (and cannot be changed), Bot Shots can. Their chest simple rotates so you can pre-set it as either blaster, sword or fist.
+ Bot Shots are transformable. You're meant to slam them into each other in vehicle mode, which triggers an automatic transformation to robot mode. Each player looks at what the other player has selected on their toy's chest and victory is determined according to what was selected.
+ Bot Shots also have Attack Strength ratings, which prevents ties. So for example if you've selected "Gun" on your toy and I've done the same, we then look at the Attack Strength -- if say your toy's rating is 390 and mine is 380, then you win.
+ Some toys come with launchers - like the Optimus Prime w/ trailer (the trailer is a battle station and launcher).
+ There are chase variants of certain toys; and rather than being just repaints, they have superior Attack Strength ratings. e.g. Super Bot 001 is a repaint of Sentinel Prime, but his stats are higher (so the chase variant will always win any potential tie).
