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.

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.
MiniMax M3.1 Flash (early version)
Visible panel shapes, curved sphere highlights, rounded side images and a lower continuation beneath the large left image establish recognizable local mirror structure. Their uneven arrangement, missing receding chains and absent nested imagery remain substantial shortcomings. The main sphere's framing is close, but black lacks projected separation and cyan does not establish recent apex contact.

A spinning metal sphere and paint in a mirrored room test physical reasoning, perspective and consistency across repeated reflections.
Visual construction and creative interpretation.


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.
MiniMax M3.1 Flash (early version)
The expressive rabbits, lavender moon and diagonal ring create an appealing storybook composition with nearly all requested features. Glossy eyes and pearly highlights work well. The helmet leaves the towering ears unenclosed, the reaching arm has little joint definition, and the spread boots suggest hovering more clearly than pushing off. Repeated scalloped fur marks and broad gradients limit material depth; purple edge halos soften otherwise controlled silhouettes.

An astronaut rabbit reaches for a carrot above a small moon while a younger companion peeks into view. The scene tests expressive characters, spatial relationships and material detail.
Precise visual recall and portrait reconstruction.


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.
MiniMax M3.1 Flash (early version)
The dark clothing, folded hands and muted landscape make the reference recognizable. Replication is limited by the broad frontal face, oversized head, explicit smile and simplified landscape. Arms connect coherently, but overlapping hands lack convincing finger construction. Soft gradients suggest volume and atmospheric depth; clothing folds and facial features remain schematic.

Creativity, perspective and visual beauty.


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.
MiniMax M3.1 Flash (early version)
A cheerful, coherent beach illustration with a strong sunset focal point, varied animals and readable small accessories. Connected flamingo legs and grounded foreground objects support the scene. Construction remains schematic, especially the airborne marine animal; its jump lacks clear water displacement. The sun reflection is effective but geometrically rigid, while shadows and material textures provide limited depth.

Scene composition and interacting subjects.


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.
MiniMax M3.1 Flash (early version)
The raccoon clearly rides on the dog's back, and the dog's paws reach a connected steering assembly. Expressive faces, controlled outlines and layered mountains make an appealing illustration. The seated anatomy and hull geometry are simplified, while the sunset has little corresponding reflection or directional shading. Curved spray conveys motion, although several splash ribbons look decorative.

Subject construction and spatial relationships.


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.
MiniMax M3.1 Flash (early version)
The large pouched bill clearly identifies the pelican, and the balanced bicycle silhouette makes the action readable. Attached legs reach the crank area, but overlapping feet and crank lines leave pedal contact ambiguous. Consistent wheel scale, clean contours and a restrained coastal palette support an appealing composition. Lighting and surface treatment remain simple and mostly flat.
