Why Groomer's Van

A slot that shows its math

Provider slots hide RTP behind studio branding. Groomer's Van is built in-house with the same provably fair receipt as Blackjack or Plinko. Six reels, scatter pays, tumbling wins, wilds, free spins, and optional bonus buy. You trade catalogue size for transparency.

Feature buys spike variance. Base spins and buy-feature RTP can differ. The rules panel shows both before you commit.

Scatter-pay slots live or die on variance. The edge number is long-run. One bonus round can define the session. Read the rules screen for base RTP vs bonus buy RTP before you spin.
How to play

How Groomer's Van works

Land eight or more matching symbols anywhere on the 6×5 grid to trigger a scatter pay. Winning symbols vanish and new ones tumble in. Wilds substitute. Four scatter symbols trigger free spins. Bonus buy is available at 125× your base bet where the lobby allows it. Max win and exact RTP for your stake tier are shown in-game before you spin.

Four or more scatter symbols trigger free spins. Tumbles continue until no new win forms on that spin. Bonus buy jumps straight to the feature at 125× base bet where your region allows it.

Tumbles chain until no new win forms. Wilds substitute on scatter pays. Free spins retrigger per on-screen rules.

Sessions

How to run a Groomer's Van session

Treat bonus buy as a separate bankroll slice. Base game flat betting keeps dead spins readable.

  • Read base RTP and buy RTP in the rules screen first.
  • Flat bet base spins unless you accept feature variance.
  • Set stop-loss in dollars, not spins.
  • Compare swing profile with Plinko high risk if you like pin-grid variance.

Strategy

Bankroll and bonus buy

This is a slot, not a strategy table. Bet size and session stop rules are the levers. Bonus buy spikes variance: you pay upfront for a feature round that can whiff or hit big. Flat betting keeps swings readable. Check the published RTP for base game vs buy feature in the rules panel.

Flat bet the base game if edge matters. Bonus buy is a variance shortcut, not a better RTP line unless the rules screen says so.
Provably fair

Verify a Groomer's Van spin

Each spin combines committed server seed, your client seed, and nonce through HMAC-SHA256. The digest maps to symbol stops on the grid. After the spin, reveal the server seed and recompute. Same flow as Crash or Dice.

  1. Before the round, copy the server seed hash from the provably fair panel. That hash is the commitment. The raw seed is hidden until the round ends.
  2. Set or accept a client seed. The nonce increments on every bet. Together they feed the HMAC-SHA256 function Duel publishes in the rules.
  3. Play the round. When it settles, reveal the server seed and recompute the digest with your client seed and nonce.
  4. Map the digest to the game outcome using the rules for that title. If your result does not match what Duel paid, open a ticket with the round ID.

What it is

Groomer's Van is Duel's scatter-pay slot in the Originals lobby. It uses the same dual-seed engine as Crash and Mines, not a third-party RNG certificate.

Practical notes

Only in-house slot in the catalogue. Table and instant titles like Mines and Crash share the same seed tools.

Recompute symbol stops for the spin from revealed seeds. Feature sequences use the same chain.
