Spin a Duel Monster Patch Notes

This patch notes page tracks verified changes to Spin a Duel Monster (place 86789126516616) by SDM Studio’s. Because the game launched around June 2026, the log starts at release and grows with each Roblox update. We note economy shifts affecting Income Tier List ranks, duel adjustments for Battle Tier List, new codes on Codes Hub, and bug fixes touching Controls Guide inputs.

How to use this log

Each entry includes:

• Date — Roblox page update or in-game verification window
• Summary — Player-facing changes
• Wiki impact — Which guides or tier lists need rereading

If an entry lacks wiki impact, the change is cosmetic or minor QoL.

August 2026 — wiki baseline snapshot

Status: Roblox marks the experience updated 30 July 2026; see the dedicated July 2026 Refresh audit. No major public economy changelog text shipped with that refresh.

Observed live features:

• Card grading and mutation systems (Card Grading, Mutations Guide)
• Duel Battle Mode queues

• Code redemption UI via ticket icon (How to Redeem Codes) with no active codes — troubleshooting in Codes Not Working
• ~199,160 visits / ~3,422 favorites (3 Aug 2026 audit)
• Official Discord: discord.com/invite/qWaB2nUvxW

Wiki impact: Initial tier lists marked as community strategy tiers pending future nerfs/buffs.

Reporting discrepancies

If live game behavior diverges from this log (example: stand income halved silently), test twice on public servers, then compare Roblox game page update timestamp. Major economy changes trigger tier list reviews within 48 hours on this wiki.

Patch day player routine

1. Read newest entry here
2. Open Updates Hub for context
3. Re-test stand income in Income Calculator
4. Scan Codes Hub even when notes omit codes—stealth code drops happen
5. Check Scripts Hub if anti-cheat mentioned

Historical policy

We never invent fictional patch numbers or fake balance tweets. Placeholder draft patches are banned from this page.

Version numbering note

SDM Studio’s may use Roblox experience version strings instead of public semver labels. When this page cites “August 2026 baseline,” we mean player-visible behavior on place 86789126516616, not an internal build ID players cannot see. If the game page update log shows a timestamp but no changelog text, we describe observed differences only after two independent play sessions confirm them—single-server glitches do not become patch notes here.
