What this game actually is

The loop is short: you draw players, you field eleven of them, and you spend Rerolls to replace the weak ones until your squad rating climbs. There is no gear, no levelling, no fusion and no pets.

That means every decision reduces to one question — which slot do I spend my next reroll on? Getting that right consistently is the whole game.

Claim the free rerolls before spending anything

You start with very little, and there is a meaningful pile of free currency available in your first few minutes. Take all of it before you make a single decision, because rerolls spent early on bad information are gone.

  • Join The LockerRoom Roblox group — this is required before any code will redeem.
  • Like the game and add it to your favourites.
  • Walk to Sendou in the lobby. He checks the like, the favourite and the group membership, then hands over ten rerolls.
  • Redeem the working codes from the codes page for roughly forty more rerolls and twenty refreshes.

Spend on your worst slot, never your favourite player

A squad is dragged down by its floor far more than it is lifted by its ceiling. Rerolling a slot that is already close to your average buys you two or three points; rerolling your worst slot can buy you twenty.

Sort your eleven by rating and always work from the bottom. This feels unsatisfying — you will be spending on players you do not care about while your favourite sits at a mediocre rating — but it is how the number moves.

Fix the goalkeeper early

Only 15 of the 214 cards in the game are goalkeepers, and unlike outfield players they cannot be covered by a card that plays multiple positions. A weak keeper is a hole nothing else fills.

If your keeper is under 70, treat it as your top priority regardless of what the rest of the squad looks like.

What the card colours tell you

Card background colour maps exactly to overall rating with no overlap, so you can read your squad's state at a glance without checking a single number.

Green50–79Replace these. 61% of all cards are green.
Silver80–87Solid. A full silver squad is a real milestone.
Blue88–93Strong. Build around these.
Orange94–98Endgame. Only 19 exist.
Red102Noel Noa, the only one.

What not to do

Do not spread rerolls evenly across the squad, do not reroll a slot twice in a row hoping for a big jump, and do not chase a specific named player early — you have no control over what appears, and the card you want may exist in five categories at five different ratings anyway.

What should I do first?

Join the group, like and favourite the game, then talk to Sendou for ten free rerolls. Redeem the working codes next. Only then start spending.

Why do my codes not work?

Almost always because you have not joined The LockerRoom group — the game checks membership before redeeming. Failing that, check capitalisation.
