DR Dominoes Guides Hub

Welcome to the DR Dominoes guides hub. This wiki covers the free mobile Dominoes app from SUD Inc. / Studio UpDown (package com.ansangha.drdominoes) on Android and iOS. Whether you want a clean rules refresher, a scoring walkthrough for Muggins, or practical advice for online matchmaking, start here and jump to the page that matches your question.

DR Dominoes uses a standard 28-tile double-six set and focuses on point-scoring variants rather than pure block Dominoes. The modes you will see most often are Muggins / All Fives, All Threes, and Fives and Threes. Offline singleplayer and online multiplayer are both available. Android has been more actively updated (notably 1.28 in July 2025); iOS builds have historically lagged (last widely noted around 1.25), so store pages and in-app version numbers are worth checking before you assume every feature matches across platforms.

Where to start

New to the app? Read Getting Started first. It covers install, mode choice, and a sensible day-one path: learn matching ends, practice All Fives, then move into scored play and online queues. Pair that with How to Play Dominoes for shuffle, hand size, doubles, the boneyard, and going out, and with Controls for tap-to-play, board view, and turn timers on phone screens.

Scoring variants

Scoring is the heart of DR Dominoes. Use these deep dives when you need exact rules instead of vague house memory:

• Muggins / All Fives — score when open ends are divisible by 5; includes spinner behavior and worked examples.
• All Threes — same table flow, but open ends that are divisible by 3 earn points.
• Fives and Threes — combined scoring when ends hit multiples of 3 or 5.
• Scoring and Spinners — math-focused companion: spinner arms, how doubles count, and end-of-hand pips.

If two pages seem to disagree, trust the variant page for that mode and use the scoring article for edge cases (especially spinner arms and leftover tiles after a hand ends).

Strategy, counting, and online play

Once rules feel automatic, shift to decision quality. The Strategy guide covers controlling open ends, blank management, and denial plays that starve opponents of easy multiples. For a dedicated deep dive on suit tracking, exposed ends, and remembering the double-six set, read Counting the Board—it is the habit that makes All Fives denial reliable. Cross-check priorities against the Tier List Hub when you want a ranked view of opening tiles, doubles, and end-control habits.

Not sure which scoring mode to queue tonight? Use Variants Compared as the chooser for All Fives vs All Threes vs Fives and Threes, then jump into the matching variant page for full examples.

Playing people instead of AI? Read Online Multiplayer for timers, matchmaking waits, etiquette, disconnects, and practical responses when a match feels unfair. Pair it with the Players Hub for opponent-facing notes and the Updates Hub when a patch changes queue behavior or UI.

How this hub is organized

Guides are ordered for a learning path, not alphabetical trivia:

1. Onboarding and core rules
2. Variant-specific scoring
3. Scoring math and spinner edge cases
4. Strategy, board counting, and multiplayer habits
5. Variant chooser and mobile controls reference

Each article aims for useful length: examples you can replay at the table, internal links to related rules, and short FAQs for the searches players actually type. Prefer practicing offline until you can spot a multiple-of-five (or three) board at a glance; online pace punishes hesitation more than imperfect theory.

Bookmark this page when you only need a map of the wiki. When a friend asks “how does All Fives score?” send them the variant guide, not a screenshot of one lucky hand. Clear rules beat vibes—especially when open ends sit on 10, 15, or 0 and someone is about to cash in.
