The Lamp of Mithila

King Janaka hands young Sukadeva a lamp filled to the brim. Carry it through the palace rooms he names without spilling a drop, then tell the king what you saw in each one. About 10 minutes, three times a week.

Your items

Buy new things from the silk merchant under the striped awning in the lotus courtyard. Tap an item here to wear it or put it away.

How to play
  • Walk: arrow keys, or hold the on-screen arrows. Left and right turn you; up walks forward. Hold Shift with left or right to sidestep.
  • Keep the lamp level: press and hold A to tilt it left and D to tilt it right, or hold the gold Tilt buttons. The oil always wants to roll to the low side, so it never stays level by itself.
  • What pushes the lamp: your footsteps, turning, breezes through the jali windows and the open courtyard, the drummer in the Dance Hall, and a startled peacock.
  • Drops: tip the lamp past the red line and oil drips. Every drop is counted and leaves a dark oily stain on the floor. Spill as many drops as your limit and the lamp runs dry: go back to King Janaka to have it refilled. Rooms don't count while you have no lamp.
  • Rooms: the king names the rooms to visit. Step inside each one and look carefully at what stands on the carpet, the carpet's color, and how many of each thing you see.
  • Report: when you've seen every room, walk back to the king's throne. He asks what you saw.
  • Same or similar? Then decide whether each treasure is exactly the one you saw, a near copy with changed colors, or new.
  • Mini map: a small map in the corner shows the palace, where you are and which way you face, with a compass. Turn it on or off with the Map button or N.
  • Pause: the Pause button, P or Esc. The game also pauses if you switch windows.
  • Difficulty: Easy, Moderate or Difficult sets the range. Your three levels still adjust inside it after each walk.
The story behind the game

Sukadeva, son of the sage Vyasa, was sent by his father to King Janaka of Mithila to learn from him. The Mahabharata tells of this visit, and the Yoga Vasistha describes Sukadeva waiting seven days at the palace gates, then seven more amid feasts and luxury, unmoved by either, before Janaka taught him.

Later retellings add the famous test: Janaka hands Sukadeva a vessel filled to the brim with oil (in some tellings, milk) and sends him through the palace. In one version he returns having spilled nothing but seen nothing. Sent again, he must notice everything and keep the lamp perfectly steady. That is your challenge.

The oil test comes from later devotional retellings, including one by Paramhansa Yogananda, rather than from the older Sanskrit texts. The sayings and the palace here are imagined for the game.

Why these tasks

Each part borrows an idea from published studies with older adults:

  • Steadying the lamp while you walk and look is multitasking practice, like the NeuroRacer driving game, where older adults trained to keep a car on the road while answering signs.
  • Exploring a 3D building and remembering what was in each room works the hippocampus, the brain's map-maker. Six months of Super Mario 64 was linked to hippocampal growth.
  • Same or similar? trains telling apart near-identical memories, the skill that improved after 4 weeks of 3D Mario but not Solitaire.

Those studies were small and short, and none showed that a game prevents dementia. This game hasn't been tested itself. Think of it as healthy exercise for attention and memory, alongside physical activity, good food, time with people, and regular checkups.
