About Luxotter: Exposure Gallery
Plan a small gallery’s display schedule with an original otter curator. Luxotter: Exposure Gallery is a 3D museum puzzle about sharing one showcase, meeting invented viewing requirements and tracking cumulative light exposure. Choose which fictional object occupies each time slot and whether its display uses Low 50 lux or High 100 lux, or leave the case Dark.
Each object starts with a prior exposure total. Every lit slot adds illuminance multiplied by hours to that object’s ledger. Earn qualifying viewing hours only when the chosen light meets its stated viewing threshold. A lower setting can still add exposure even when it earns no viewing credit. Darkness adds nothing, but never removes prior exposure or reverses fading.
Explore 180 studies across First Displays, Shared Showcase and Exposure Curator. Easy shares three slots between two objects; Medium shares four between three; Hard fits four objects into four slots. Read the different slot lengths, compare each object’s remaining exposure allowance and assemble any schedule that meets every requirement. All satisfying schedules are accepted, with no hidden optimum.
The objects, viewing thresholds and exposure budgets are invented lesson values. The model separates cumulative illuminance-time from electrical energy and does not establish real conservation safety. Objects outside the showcase are assumed to stay in dark storage.
Preview the selected slot in the 3D case and check the whole-schedule ledger. Undo edits, clear the plan or request a hint that highlights a possible slot change without applying it. Earn up to three stars per study and retain best results, course position and sound preference on this device when browser storage is available.
How to Play Luxotter: Exposure Gallery
Choose First Displays (Easy), Shared Showcase (Medium) or Exposure Curator (Hard). Each course has 60 studies. Easy offers two objects and three time slots, Medium three objects and four slots, and Hard four objects and four slots.
Read the slot durations and every object’s prior exposure, cumulative exposure budget, viewing threshold and minimum qualifying hours. Only one object can use the case in each slot. All other objects remain in dark storage in this simplified model.
Select a time slot, choose its object and set Low (50 lux) or High (100 lux). Choosing an object from a Dark slot initially uses Low; adjust it to High when needed. Choosing Low or High from a Dark slot uses the first object, shown in the preview. Choose Dark to leave that slot’s case empty. The 3D case previews only the selected slot, while the ledger totals all slots.
For each object, add lux × hours from every lit display to its prior exposure. The cumulative total must be at or below the invented budget. Separately add the hours of displays that meet or exceed its viewing threshold. Low below a 100-lux threshold still adds 50 × hours of exposure but earns zero qualifying hours. Dark adds zero exposure and zero viewing time; prior exposure remains unchanged.
Use Check gallery schedule when every object meets both requirements. Any satisfying schedule is accepted. Undo edit restores the previous slot setting. Clear schedule returns all slots to Dark while retaining unsuccessful checks and hint use. Curator hint highlights a possible slot change without scheduling it for you.
Desktop: 1–4 selects an offered time slot, A–D chooses an offered object, 0 makes the selected slot Dark, 5 sets Low and 6 sets High. Enter checks the schedule or continues after success when the gallery has focus. Z undoes an edit, R clears the schedule, H requests a hint and M toggles sound. Escape closes help. Tab and Enter activate focused controls normally.
Mobile: tap a slot, then an object card or its 3D shelf label, and tap Dark, Low or High. Use the on-screen checking, undo, clear, hint and sound controls. Actions use direct buttons without form submission.
Three stars require no unsuccessful checks or hints; two stars allow up to two unsuccessful checks and no hints; every completed study earns at least one star. Best stars are retained on replay. These are fictional exercise budgets, not universal safe museum limits.
