Most bad sessions don’t come from math—they come from momentum. The 2-Block Method turns any game (slots, crash, live tables) into two focused windows of 12–15 minutes each, separated by a cooldown. You play with a flat unit (1–2% of bankroll), fixed rules, and a written exit—so decisions stay steady while the game swings.

Block A: Calibrate

• Unit: pick 1–2% and don’t change it mid-block.
• Scope: one primary game/market; side features ≤10% of the unit.
• Goal: log pace (hits per 100 spins / hands), note mood (1–5), define exits.

Block B: Execute

• Profit stop: +2 units → skim 50% to a vault; continue only if rules are intact.
• Loss stop: −3 units → end the day; no “one last try.”
• Cooldown: 2–3 minutes off-screen between blocks (water, stretch, reset).

Bankroll & rhythm that actually hold

Flat staking beats “feel.” Peaks are banked immediately; dips trigger the plan, not a chase. Treat RTP as long-run guidance and let volatility shape experience, not stake size. For additional guardrails, see the UK Gambling Commission guidance.

Edge log: one minute that compounds

• Game/market, start balance, end balance, new peak.
• Hit rate / tempo notes (fast, medium, slow).
• Mood 1–5 and one sentence: “What I’d repeat tomorrow.”
