Anticipating threats and planning ahead. Collect coins while avoiding ghosts. Ghosts move before the player each turn, and collisions cost a life. 3 levels in sequence, up to 66 turns in total. Earlier moves and outcomes carry forward, testing learning across levels.


Cooperative planning and learning from experience. Coordinate two robots to push numbered cores onto matching sockets. Pressure plates hold doors open; moving either robot uses one turn. 5 levels in sequence, up to 152 turns in total. Earlier moves and outcomes carry forward, testing learning across levels.

Ling 3.1 Flash
Central placement, separate airborne black paint and the elongated crimson coating earn substantial state and placement credit. Cyan contact remains unresolved. A few isolated sphere images provide limited optical evidence, while the defining repeated mirror structure is missing. Readable opaque metallic volume and restrained paint scale justify increased material credit. Core: 61.5/170; including the floor reward: 61.5/180.
Muse Spark Open
The airborne black blob and deformed paint support the broad contact sequence, although cyan attachment and wheel-directed transport remain partial. The sphere and black blob have substantial framing errors. The dominant limitation is the largely absent mirror system: faint wall circles and isolated highlights provide little evidence of recursive room geometry or curved nested reflections. Oversized compact paint features and diffuse material treatment further limit credit.

Ling 3.1 Flash
An appealing, coherent storybook ant with a clear expression, complete silhouette and readable signal mechanism. Clean curves and warm accents support the composition, while simplified joints, schematic hardware, limited material differentiation and modest light interaction constrain its finish.
Muse Spark Open
The rounded silhouette and asymmetric expression make an appealing baby elephant, supported by a quiet background and grounding shadow. The protective action remains difficult to read: forefeet cannot be confidently traced into a grip, and seed contact is crowded by fine lines. Controlled simple shapes provide charm, but limited anatomical clarity, shading and surface detail leave the execution uneven.

Ling 3.1 Flash
A basic, uneven Mona Lisa interpretation with a clear facial focal point, articulated eyes and modest tonal volume. Weak likeness, oversized head proportions, unclear shoulders, curled bare arms and indistinct hands limit replication. The compressed composition and rectangular torso weaken an otherwise coherent earthy palette.
Muse Spark Open
A recognizable, orderly interpretation with clean major contours, connected body forms and modest facial shading. Wide eyes, frontal symmetry and schematic hands limit likeness and expression. Layered scenery establishes basic depth, but shallow arm overlaps, flat clothing and sparse fine detail keep the execution basic and uneven.

Ling 3.1 Flash
A coherent sunset illustration with harmonious color, clean silhouettes and readable beach details. Its calm composition works well, while playful activity is modest. Simplified animal anatomy, shallow shoreline layering, repetitive foliage and a geometric reflection limit drawing sophistication and naturalism.
Muse Spark Open
A coherent sunset beach with readable activities, balanced framing and controlled colour transitions. Small accessories add interest, but schematic anatomy, limited surface detail, weak directional shadows and a geometric reflection constrain its finish. Most shapes and overlaps remain clean.

Ling 3.1 Flash
An appealing sunset cartoon with recognizable animals, expressive faces and coherent landscape layers. The sky and warm water streaks provide its strongest rendering. Ambiguous seated support, stiff forelegs, a shallow hull and an unclear steering connection limit construction. Clean shapes and readable accessories add finish, while restrained spray and flat surfaces limit material and motion effects.
Muse Spark Open
Expressive faces, distinct accessories and clean color separation make the scene appealing and recognizable. Character detail is stronger than the functional construction: steering contact, limb overlaps and seating remain ambiguous. The readable hull and lively spray establish motion, while limited directional shading and simplified surfaces constrain depth and physical coherence.

Ling 3.1 Flash
A clean, appealing pelican illustration with a readable bicycle and coherent landscape. Bill shading, feather layers and faint wheel shadows provide modest depth. Uncertain pedal contact, simplified leg construction and limited material rendering keep the result within competent illustration quality.
Muse Spark Open
A controlled, appealing cartoon with a recognizable pelican, expressive face and clean curved forms. Feather lines, spokes and bill shading provide useful complexity. Aligned wheels and a ground shadow establish placement, but uncertain pedal contacts and obscured mechanical connections weaken support and riding action. Lighting remains loosely coordinated with the sun.
