The Unbreakables Challenge 3 SBC is the final puzzle-style Squad Building Challenge in the FC 26 Unbreakables promo. It is designed as a low-rated fodder sink that rewards smart club management with a high-value pack. You only need one squad, but the chemistry requirements are tighter than many early-game SBCs.
By completing this SBC before it expires in FC 26 Ultimate Team, you earn an untradeable Mega Pack, one of the most rewarding standard packs in the game. Because the Winter Re-Release batch is in packs with 60+ special items available, this challenge is a good opportunity to turn unwanted fodder into a potential walkout or promo card.
This guide breaks down every requirement, provides an example squad solution, and explains how to finish the SBC cheaply without draining your club or overpaying on the transfer market.
The SBC consists of only one segment, but the puzzle is all about balancing league, club, and nationality restrictions while maintaining enough chemistry.
You must build a single 11-player squad that meets all of the following conditions:
The chemistry requirement of 31 is the main hurdle. You will want to concentrate players from the same league and region while making sure you do not exceed two players per club. A hybrid of two strong leagues (for example, LaLiga + Premier League or Serie A + LaLiga) usually works well.
To satisfy these conditions without overspending, consider the following approach:
If you build around what you already own in your club, you can often complete this SBC with minimal or even zero coin spend.
Below is an example solution that satisfies all the requirements. Exact prices will vary with market fluctuations, so use this as a structural template rather than buying the exact players at inflated prices.
The original sample solution uses a mix of mid-70s and low-80s players with good league and nationality coverage:
This combination hits the required rating and chemistry by using multiple clubs within one or two leagues, adding a few higher-rated players to carry the overall rating while some lower-rated cards fill the remaining spots.
You do not need these exact players. Instead, mirror the pattern:
Start by filling the squad with untradeables from your club. If you are short in certain positions, then search the transfer market for the cheapest players that match the required league and rating. This is usually more efficient than copying one solution card-for-card, because prices on highlighted SBC players can spike.
Once you submit the squad, you receive an Untradeable Mega Pack. This is one of the best standard packs available in FC 26 Ultimate Team for the cost of a low-rated SBC.
The reward includes:
Although the pack is untradeable, it has a high chance to boost your club depth, especially if you need more fodder for future SBCs or want to improve a weaker area in your squad with a couple of 82–84 rated cards.
During the Winter Re-Release period, more than 60 promo cards are available in packs. Opening an untradeable Mega Pack at this time gives you a realistic shot at:
Because you are trading mostly low-rated fodder for a chance at high-value cards, this SBC is well worth completing for anyone regularly playing Ultimate Team.
To squeeze the most value out of Unbreakables Challenge 3, try to minimize how many coins you spend on the solution. Here are some practical ways to do that.
Before buying anything, check your club for:
Pair these untradeables first and only use the market to fill gaps. This is especially important if you are saving coins for icons, heroes, or other big investments.
When you do need to buy players, focus on:
Consider doing this during times of higher pack supply (like lightning rounds or new content drops) when many players are listing cards and prices temporarily drop.
Do not toss every mid-rated card into this one challenge. Because the reward is untradeable, you may want to preserve some 82–84 rated players for future:
Keep your best fodder for SBCs that yield tradable packs or guaranteed special players. Use your least useful rare golds and lower-rated silvers here instead.
