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.
