Two-Direction Bias Explained: Stability Through Constraint

Why It Works

Limiting moves to two orthogonal directions maintains a consistent compression pattern, keeps the anchor edge ordered, and reduces spawn chaos.

Choosing Your Pair

Pick the pair that compresses toward your anchor (e.g., Left and Up for a top-left anchor). The third direction is reserved for planned merges; the fourth is emergency-only.

Measuring Discipline

Track unplanned presses per game—aim for zero.
Count how often edge order breaks after using the third direction.

Drill: Play a session where you may only press your two chosen directions unless a merge is guaranteed otherwise.

Adopt two-direction bias and your consistency will rise. Play now.
