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.

DeepSeek-V4.1-Flash-1017
Principal sphere and airborne-black placements are supported, and diminishing bilateral chains provide limited optical structure. Missing nested imagery, incomplete outer chains, distorted first images and sparse emitter recurrence remain the dominant weaknesses. Oversized paint bodies and unresolved cyan contact impose separate limitations.
MISSINGNO.
The centered sphere, separate airborne black blob and cyan-above-crimson ordering provide limited valid structure. The colored beads do not establish the required impact and transport histories. One dim floor image supports a small part of the optical system, while the defining wall repetitions, nested sphere imagery and emitter mappings are missing. Rounded volume and some gloss earn material credit, tempered by soft surface appearance and excessive paint-bead scale.

Visual construction and creative interpretation.


DeepSeek-V4.1-Flash-1017
An expressive, intricately drawn storybook scene with a complete flowing silhouette and differentiated glossy materials. The supported main lens and continuous shrimp body make the central interaction readable, but reciprocal eye lines, facial magnification and the smaller lens grip remain ambiguous. Bright granular fringes and crowded accessory lines limit the finish.
MISSINGNO.
An appealing purple character with a readable pleased expression and raised-moustache joke. Smooth shading and clean contours support the simple design, but indistinct mitten grips, minimally textured curls and an uncompressed strap weaken the requested physical interaction. The jelly suggests gloss more convincingly than translucency.

DeepSeek-V4.1-Flash-1017
A whale and a tiny shrimp examine one another through bubble lenses, with an octopus nearby. The scene tests interacting characters, differences in scale and transparent materials.
MISSINGNO.
A glossy purple jelly struggles with an oversized fake moustache at a playful checkpoint. The scene tests comic expression, physical contact and the appearance of a soft translucent body.
Precise visual recall and portrait reconstruction.


DeepSeek-V4.1-Flash-1017
A coherent graphic interpretation with controlled contours, modeled facial volume and purposeful portrait details. Replication remains limited by the frontal pose, enlarged face, altered expression and ambiguous crossed hands. Landscape layering provides depth, while schematic fabric, smooth surfaces and tonal bands constrain the finish.
MISSINGNO.
Clean contours, connected body forms and gentle gradients support a basic, coherent portrait. Likeness remains weak: the face dominates the body, the seated angle is lost, and crossed hands become dark lobes without traceable wrists or fingers. Readable facial details add some drawing complexity, but clothing, landscape and material treatment remain sparse.

Creativity, perspective and visual beauty.


DeepSeek-V4.1-Flash-1017
A coherent, colorful beach illustration with controlled curves, clean layering and varied readable accessories. Castle details and small animal features strengthen its finish. Schematic airborne animals, uncertain board support, shallow architectural depth and decorative reflections limit physical coherence and drawing sophistication.
MISSINGNO.
A coherent sunset beach with clear requested subjects, balanced framing and clean shapes. The aligned solar reflection and warm gradients establish atmosphere. Primitive animal construction, ambiguous furniture, sparse depth cues and minimally developed surfaces limit its drawing complexity and physical richness.

A plank, computer mouse and blueberry in a steel room test physical stability, spatial relationships, materials and lighting.
Scene composition and interacting subjects.


DeepSeek-V4.1-Flash-1017
An appealing cartoon with recognizable riders, expressive faces and a cohesive twilight palette. Clean shapes support the composition, but ambiguous limb overlaps, weak seat contact and loosely resolved steering limit physical coherence. Lighting and water effects are decorative, with modest material differentiation and drawing complexity.
MISSINGNO.
The requested interaction reads clearly through recognizable animals, expressive faces and a coherent hull-water relationship. Clean curves and readable accessories give the cartoon polish. Partly unresolved grips and supporting contacts limit physical construction; modest shape complexity, weak directional lighting and schematic water constrain its finish.

Subject construction and spatial relationships.


DeepSeek-V4.1-Flash-1017
An expressive, controlled illustration with continuous body construction, substantial bicycle detail and effective landscape depth. Unclear foot-to-pedal and wing-to-handlebar contacts limit physical conviction and local readability. Purposeful detail and composition are stronger than directional lighting and material treatment.
MISSINGNO.
A coherent, cheerful illustration with recognizable pelican features, balanced composition, clean contours and useful small details. Its controlled curves and layered wheels demonstrate competent drawing skill. Ambiguous pedal and steering contacts, sparse drivetrain construction and weak directional lighting limit the riding mechanics and finish.
