How to Get Trait Rerolls in 8 Bit Tower Defense (and Where to Spend Them)

Last updated:

Trait Rerolls come from codes, the Roblox group reward and the hub tutorial in 8 Bit Tower Defense. Here's where to claim them and how to spend them in a unit's TRAITS tab.

Quick answer

You can get Trait Rerolls in 8 Bit Tower Defense from redemption codes, the Roblox group reward in Settings, and a one-time grant from the in-game hub tutorial. You spend them on a unit you own — open that unit's detail page, open its TRAITS tab, and press REROLL to roll a new trait with a dice.

  • Redemption codes award Trait Rerolls; the current working list is kept on the site's Codes page.
  • The Roblox group reward in Settings pays +1 Trait Reroll once you have joined the group and liked the game.
  • The hub tutorial's unit-leveling step granted 2 Trait Rerolls (alongside 500 gold) as a one-time bonus.
  • Traits add damage, range, cash and more — an observed reroll produced SWIFT I (5% faster attacks).

Trait Rerolls are the consumable you spend when you want a different trait on one of your units. Traits are a core part of the game — the official description sums it up as "Roll traits and hunt for Shiny units" — and they add damage, range, cash and more to a unit. This guide covers every supported way to get more Trait Rerolls and exactly where the reroll button lives.

How to get Trait Rerolls

1. Redeem active codes. Open Settings and use the "CODES: Enter a code -> REDEEM" field. As of November 12, 2026, codes such as UPDATE1, HALLOWEEN and HALLOWEENPT2 are reported to pay out Trait Rerolls (alongside Gems and other resources). Code availability and rewards change over time, so check the maintained 8 Bit Tower Defense codes list for the current amounts before you type one in.

2. Claim the Roblox group reward. In Settings, right next to the CODES field, there is a "Join the Roblox group" offer with a CLAIM button. Once you have actually joined the Roblox group and liked the game, claiming pays +100 Gems and +1 Trait Reroll. If you have not done both yet, the claim will not pay out, so join and like first.

3. Follow the hub tutorial. During the hub walkthrough's unit-leveling step ("STEP 4/6: Gold from battles levels up your units"), the game grants 500 gold and 2 Trait Rerolls. This is a one-time tutorial grant, observed alongside the 500 gold during the hub walkthrough.

Where to spend Trait Rerolls

  1. Open your UNITS and pick a unit you own — the reroll action lives on the unit's detail page.
  2. Open the TRAITS tab on that page. That's where Trait Rerolls go.
  3. Press REROLL. The game rolls a new trait with a dice.
  4. Read the result. In the observed tutorial reroll, the dice produced SWIFT I — 5% faster attacks.

Because Trait Rerolls are a consumable, every press of REROLL uses one up, so it makes sense to think about which unit you are rolling for. Observed trait effects include damage, range and cash bonuses — for example, a faster-attack trait like SWIFT I directly increases how much damage a unit puts out over time. If you want a deeper look at what traits do and how they interact with the rest of a unit's stats, the 8 Bit Tower Defense traits guide goes into the system in detail.

Turn on the reroll confirmation

Settings > GAMEPLAY includes an "Ask before trait rerolls" toggle, sitting alongside "Ask before traits" and the other gameplay options. Switch it on and the game asks for confirmation before each reroll — a cheap safeguard for a consumable resource, since one accidental press otherwise spends a reroll immediately.
