URBAN RATSSKILL GAMES

Skill-based iGaming studio

Games where skill decides.

We build mobile-first, wagering-style games in which the result comes from your decisions — where you place, what you clear, when you stop — not from a spinning reel.

Our principles

Skill first. Luck kept small, and provable.

Your decisions drive the outcome

Every placement, every line cleared and every cash-out call is yours. Better play reaches further — measurably.

Randomness you can verify

The only random element is which pieces you are dealt. It is committed before you play and can be checked after the round.

Same rules for every player

Published rule configs. The generator never sees your balance, your winnings or your decisions.

Built for the phone in your hand

One-thumb controls, 60 fps effects, haptics, reduced-motion and sound options.

How a round works

From stake to verified result

  1. 01

    Choose difficulty & stake

    Demo credits only. Each difficulty publishes its multiplier table and when cash-out unlocks.

  2. 02

    Play the levels

    Clear the required hands to finish a level. The board carries over, so planning ahead pays.

  3. 03

    Cash out or continue

    After each level you choose: take the current multiplier, or risk it for a higher one.

  4. 04

    Verify

    When the round ends, the server reveals its seed. Recompute every hand you were dealt.

For partners

Engineered like a payments system

The game engine runs on the server. The client only sends intents; the server validates every move, settles cash-outs once, and keeps an append-only, hash-chained history.

Read the developer overview
  • Server-authoritative engine, shared with the client for animations
  • Idempotent actions and optimistic concurrency
  • Hash-chained action log, append-only ledger and audit trail
  • Abandoned sessions resolved by clear, published rules
  • Prometheus metrics and alert rules
