4-wide construction patterns

From TetrisWiki
(Redirected from Modular construction)
Jump to navigation Jump to search

These are 4-wide building patterns but with a few rules:

  • No I pieces are to be used in any pattern.
  • The patterns only take duplicate next pieces into account. Triples are not possible with Random Generator.
  • No figures will lead to a 020 end pattern because that will force the need for an I-piece.
  • No soft dropping.
