Maxwell Cadman Scoring you can trust
Every combination — ones, fives, triples, straights and specials — resolves deterministically, and the in-game rules screen lets a player check any result against the dice they kept.

Riverboat Zilch
Push-your-luck dice done as a polished modern classic. Keep the scorers, build the pot, and decide when to bank — solo against distinct rivals, around one phone, or on connected tables for two to six players.

01
The design problem
A familiar game has nowhere to hide.
Everyone who plays a 10,000-style dice game already knows the rules, so the product cannot win on novelty. It has to win on feel, fairness and the quality of the table — and any scoring mistake is immediately obvious to the player.
Rivals worth meeting
Four AI regulars with distinct risk appetites turn the solo voyage into a series of opponents rather than a string of score targets.
Tension in the hand
Flick, settle, select, bank. The whole interface exists to make one question — stop or roll again — feel physical.
Fair by construction
Cosmetic dice and felts never affect odds, and connected tables use preset reactions instead of free-form chat.
02
Engineering and release
Exhaustively verified, then made to survive a bad connection.
Because the scoring rules are finite, they can be proven rather than sampled. Every possible roll of six dice — all 46,656 of them — is evaluated against the scoring table in test, so a scoring regression cannot reach a build.
Exhaustive scoring tests
All 46,656 six-dice outcomes are verified against the expected scoring result, making the rules engine provably correct rather than spot-checked.
Server-authoritative online
Match state lives on the service, not the client. A dropped connection reconnects into the same match instead of forfeiting it.
Recoverable guest profiles
Online play needs no account: a pseudonymous installation identity carries ratings and history, stored as a hash rather than personal data.
Offline is the default
Career, Quick Match, Daily Roll and Pass & Play all run with no connection and no account at all.
