Not every slot fits short sessions. This practical RTP & volatility map helps you pick titles for 12–18 minute blocks with a flat 1–2% unit. Track a tiny set of metrics, set clear exits, and convert “nice spins” into a tidy curve.

1) The map: three bands, one purpose

• Green (Low–Mid Vol): high hit-rate, steady minis (2–5×). Best for WR tasks and warm-ups.
• Amber (Mid Vol): balanced minis and features. Daily driver for most blocks.
• Red (High Vol): sparse base, explosive features. Use only with firm stops and a smaller unit.

2) Minimal metrics you actually use

• C/100 (cost per 100 spins): (start−end) ÷ (spins/100). Rising >20% vs. your norm = switch slot.
• Mini-wins/100: count of 2–5× hits. <5 per 100 ⇒ expect choppy blocks.
• Feature rate (rough): spins per feature during a block. Plan breath accordingly.

3) Unit & tempo: keep the engine calm

• Flat unit: 1–2% of bankroll per spin; no step-ups mid-block.
• Block timer: 12–18 minutes on, then 2–3 minutes off screen. The clock closes the block.
• Daily stops: end day at +2 units or −3 units from the day’s peak — whichever first.

4) Picking today’s slot (60-second checklist)

1. Open demo for 100 fast spins — note minis and rough feature pace.
2. Label the slot Green/Amber/Red for today, not forever.
3. Set stake = 1–2% unit and start the block. No stake edits.

5) Vault rule: keep what matters

On any new day-peak, move 20–30% into a “vault” (separate wallet or ledger) and do not reuse it the same day. Peaks become progress, not longer sessions.

6) Frequent mistakes (and quick fixes)

• Chasing a “Red” slot with a “Green” unit: fix by cutting stake or switching to an Amber/Green title.
• Changing slot and stake at once: fix by altering one variable per block.
• Ignoring C/100 drift: fix by pausing or swapping when cost climbs >20% above baseline.
