Use short, decisive swipes rather than long arcs to reduce accidental diagonals. Keep your thumb near the board edge to shorten travel distance.
Commit to a two-direction rhythm (e.g., Left–Up) and practice alternating swipes at a steady tempo to maintain tile order on small screens.
Rest the device on a surface to stabilize hands. Play in 10–15 minute sessions to avoid fatigue-induced mis-swipes.
