Block generators: the board keeps growing

Generators spawn new blocks over time, so a board that looks open can fill up if you only react instead of clearing.

MECHANIC RULES

How Ivy works

  • Block generators add new blocks to the board on a schedule rather than all at the start.
  • The App Store listing names block generators among the game's dynamic obstacles.
  • Each spawned block takes board space that you must eventually route to an exit.

DECISION PRIORITY

Strategy checks

  • Clear the oldest, most blocking pieces first so generators do not pile up space.
  • Keep at least one lane open as a buffer for incoming blocks.
  • Prefer routes that remove a generator's neighbor before the next spawn lands.

AVOID

Common mistakes

  • Do not wait for a perfect move while generators keep adding pieces.
  • Do not box yourself into a corner where new blocks have nowhere useful to go.
  • Do not ignore a generator just because the current board still looks comfortable.
