[^1]\n\nThe study shows that current scene synthesis approaches achieve at most 10% success rate in LEGO-Eval. [^2]\n\nBrick Search is running a competition that awards a £500 LEGO e-gift card to one winner, with entries accepted until 4 October 2026. [^3]\n\nThe competition celebrates the release of the new Shrek Minifigures on 1 September 2026. [^4]\n\nLEGO-Eval is an evaluation framework that decomposes a description into atomic constraints and verifies each one using tools that ground textual references to 3D objects and reason about their spatial relationships. [^5]\n\nThe study highlights that existing evaluation methods for text-guided 3D scene synthesis either capture only coarse similarity between the synthesized scene and the user description or ignore the spatial reasoning for verifying object placement. [^6]\n\nBrick Search's Brick Credits loyalty programme provides members with unlimited scanner access and an additional 3% back in Brick Credits when shopping at LEGO.com via the app. [^7]\n\nThe £500 LEGO e-gift card prize is redeemable online at LEGO.com, in person at official LEGO Stores, or by phone.
