BiRS

Bias Rotation System, an original rotation system used in Techmino based on XRS and SRS. In BiRS, an extra offset is triggered when either the left, right, or softdrop key is pressed and the block touches the minoes or walls in that direction. This introduces an additional offset in the specified direction, in addition to the standard offsets listed on the wall kick tables. The horizontal extra offsets indicated by the keypress must not be in the opposite direction to the composite horizontal offset, and the distance of the composite offset must not exceed √5. If the test fails, the system will perform another test without the horizontal offsets; should this also fail, a further test will be conducted without downward offsets. In contrast to XRS, BiRS uses only a single kick table, making it easier to memorize while retaining the climb-o
