Turbo Flip (Pinball)

Turbo Flip is a neon-arcade pinball mini-game. Each ticket launches one ball; the player keeps it alive with two flippers, racks up points off bumpers, slingshots, drop targets and the spinner, then the ball drains and the score lands on a leaderboard. Top scores win bonus site credit, same pattern as Sky Run.

How it’s wired

• Canvas-rendered playfield (portrait, 400×700 reference units) with a deterministic fixed-step physics simulator running at 60 Hz. Same simulator code lives client-side and worker-side so every submitted run can be replayed for verification.
• Action log: every plunger / flipper press is recorded with a sim-time timestamp. On submit, the worker replays the log, recomputes the score, and stores min(claimed, computed). Cheaters get silently clamped to whatever their inputs would have actually produced.
• Anti-cheat: single-kick-per-press flipper rule (spamming the button doesn’t inject extra energy), monotonic action timestamps required, exactly one plunger fire per ball, and a 40-input-per-second rate cap.
• Procedural chiptune music + a mute toggle. Audio context is lazy-loaded on the first user gesture to satisfy mobile autoplay policy.

Scoring + combos

• Bumpers, slingshots, drop targets, spinner, and ramps each award points. Combo multiplier scales 1× → 5× as the player chains hits within a 500 ms window.
• Clearing all three drop targets in a row triggers FRENZY mode (3× score for 10 s) and an inline pop-up.
• Hitting max combo (×5) unlocks POWER BALL for 5 s: every scoring event gets +50 on top of the multiplier. Re-triggering extends the timer. Visual: rainbow halo + multi-coloured ball trail + countdown bar in the HUD.

When to use it

• Audiences who want a longer, skill-rewarding session: Turbo Flip has the deepest skill ceiling of any mini-game on the platform.
• Mid-to-high-value competitions (£10+ per ticket equivalent). The 60-second-ish session time justifies the engagement.
• Strong on mobile portrait. The playfield fits cleanly on a phone in portrait orientation, while desktop letterboxes.
• Skip on quick-fire 50 p instant-wins (too much friction for the revenue).

Per-competition setup

Pick Turbo Flip from the Mini Games dropdown in the competition edit page (Instant Win Customisation block). Pick an optional theme colour or preset gradient, which bleeds into the playfield background, the card hero, the detail-page hero, and the checkout animation backdrop. The theme also tints the in-game sky (the canvas background) so the gameplay matches the rest of the journey.

Leaderboard prizes can be configured per competition: top N scores get bonus site credit; the rest of the prize pool follows the standard random-distribution model. The card & detail page automatically show the leaderboard pane once at least one score has been submitted.
