Degenerate Strategies & Runaway Leaders

A line of play so strong or safe that other options stop being worth considering — it dominates and shrinks the decision space.

A feedback problem where being ahead earns more rewards, so the winner is predictable early but the game keeps playing.

Players are optimizers; finding the shortest path to victory is information that tells you where your design collapses.

Turtling, hoarding, or infinite loops — not the strongest play, but unbeatable and unfun; interesting decisions still evaporate.

Log players' first 2-3 actions each game; if one opening appears in over 60% of games (or winners' openings are less varied), you've found the highway.

Ban the suspect strategy for one session. Richer game = it was crowding out fun. Aimless game = it was load-bearing and needs a replacement first.

Plot each player's score per round. Healthy games show crossing lines and late reversals; a runaway leader diverges with a gap growing faster than remaining rounds can close.

A counter-option turns a dominant strategy into a rock-paper-scissors relationship, which has no dominant move — only a mixed equilibrium.

Nonlinear cost/payoff curves (e.g. 3n − 0.4n² instead of 3n) permit the strategy but cap its abuse, peaking around n = 3-4.

Some strategies are degenerate because they're fast, not strong; a delay or setup cost makes them a real commitment.
