The LEGO® BOOST playmat
The playmat is an important part of the LEGO® BOOST experience. It's needed for the three models that can move around (the "getting started" vehicle, Vernie and the M.T.R.4). The playmat contains a grid that's calibrated to the movement commands in these models. One move block in the coding enables the model to move one square on the grid of the playmat.
