Boomer Bill Barrage

"With a BrickScore of 62.5, Boomer Bill Barrage is a crowd-pleaser for young Mario fans and families but a middling pick for discerning builders — the clever spinning mechanic and iconic characters win hearts, while vague minigame instructions, app dependency, and a premium price hold it back from being a must-buy expansion."

The LEGO Super Mario 71366 Boomer Bill Barrage is an expansion set that earns genuine enthusiasm from family buyers for its fun spinning Boomer Bill mechanic, vibrant build, and strong interactive app integration — but draws measured criticism from more analytical reviewers for unclear minigame instructions, limited long-term play value, and a price point that feels steep for 132 pieces. The majority of owner reviews are overwhelmingly positive, while dedicated LEGO reviewers flag specific design shortcomings that temper the overall verdict.

Where they split: Owner/family reviewers were nearly unanimous in giving top marks and recommending the set enthusiastically, while the dedicated LEGO reviewer (Brick Fanatics) landed at a notably lower score and recommended skipping it in favor of 71365 Piranha Plant Power Slide. The split largely comes down to whether you evaluate it as a fun toy experience (positive) or as a well-executed LEGO product with clear gameplay design (mixed).
