The blocks used to build complex logical expressions (conjunction – both conditions are true, alternative – one of the conditions is true, negation – contradiction). Insert the matching blocks returning Boolean values (true or false) in argument boxes. Blocks are used most often in the following instructions: '''if, repeat until, wait until'''.

The block is used to connect two strings of text into one. Usually one of the arguments is the entered text, and the other a value returned by another block. The block is often used as an argument in the '''say ''' and '''think ''' blocks.
