Build a Bridge Together Update 13 Summary
Event and pets content, codes reminder, and post-patch grind order.
What Update 13 means for your grind
Update 13 sits in the mid-era patch wave for Build a Bridge Together—the same stretch of content that also brought summer-event energy (Update 10), obbies and achievements (Update 11), and ongoing pet/event drops. Creator coverage for Update 13 focuses on event wrappers and pet content layered on the familiar smash → bridge → hatch → rebirth loop. Always confirm the live list in the in-game update log after you join; wiki pages summarize themes, while your client is authoritative.
Use this page as a dedicated Update 13 briefing, then keep Latest Update and the Updates Hub bookmarked for habits that apply after every patch.
Event and pets focus
Update 13-style messaging emphasizes limited-time event framing and pet rewards rather than replacing the simulator fantasy:
- Expect event UIs, timed tracks, or showcase pets that compete with your current Tier List keepers.
- Compare live multipliers before dumping shiny treats, rainbow crafts, or evolution gems into a brand-new exclusive.
- Fold winners into the normal Pets Guide pipeline (equip best → shiny → rainbow → evolution / ethereal when available).
- Treat missable event cosmetics as optional; never pause rebirth percentage just to stare at a banner.
If an event egg or machine appears in a specific world, unlock that island with wins first—events rarely waive bridge gates.
How Update 13 fits Updates 10–11
Reading patches in order helps:
- Update 10 — summer-event style content and seasonal framing (community video coverage around that drop).
- Update 11 — dual obbies, deeper achievement boards, limited pets, secret codes, UI polish (see Latest Update).
- Update 13 — continues the event/pets push on top of those systems.
You do not need to “catch up” every historical banner. You do need achievements, codes, and pet craft habits that still ship in today’s client.
Codes checklist after Update 13
New patches often retire old strings and sometimes add secret codes. As of the consensus list tracked on this wiki (September 2026), redeem:
| Code | Notes |
|---|---|
IMSTANDINGONATREE | Free Rewards |
SECRETBRIDGE | 10 Gems |
Release | 1 Shiny Treat + 3 Gems |
TBLOX | Magic Dice II |
Expired update-branded codes such as UPDATE12, UPDATE9, UPDATE6, and Update5 should not be retried—full tables on the Codes Hub. Redeem via Settings → Redeem (How to Redeem).
Post-patch session order
- Open the in-game update log and skim event timers.
- Redeem active codes; equip any new gadgets (Dice II from TBLOX still matters).
- Claim daily / playtime / group rewards and join TBlox Mini if needed (Friend Boost).
- Peek achievements and event pet goals you can finish quickly.
- Run new or leftover obbies once if limiteds still matter.
- Resume smash → auto build → rebirth in your best world.
- Invest event pets only if multipliers beat your current team.
What not to do after the patch
- Do not hoard millions of wins “until the event ends”—percentage still compounds smash speed during events.
- Do not delete strong non-event pets to make inventory space without a craft plan.
- Do not trust random comment codes; verify on Codes or official channels linked from Official Links.
- Do not assume scripts survived the patch (Scripts disclaimer still applies).
