The Lantern Suite

Ten games. Each one pairs a well-studied cognitive exercise with a living tradition from across Asia and the Pacific. Each runs offline, in a single small file.

Open the full suite

Saffron & Silk

Notice the edges without losing the center.

Keep your eyes on a singing bowl while a silk pouch flashes at the edge of view. Report the pattern in the bowl, then where the pouch appeared.

Practices: Visual processing speed
Research model: Useful field of view (UFOV) and inspection time, with an adaptive staircase
Cultural anchor: Himalayan brass singing bowls and the saffron silk trade of South Asia
Why it matters: Speed-of-processing practice has the strongest long-term evidence of any brain-training domain. Here it is framed as calm, chosen attention rather than constant scanning.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Saffron & Silk

Batik Matrix

Hold the pattern, then weave it back.

Tiles of undyed cloth briefly reveal a batik motif. Remember where, then tap them back from memory as the grid grows.

Practices: Visual-spatial working memory
Research model: Spatial span recall on growing grids, with adaptive load
Cultural anchor: Wax-resist batik of Indonesia and Malaysia
Why it matters: Spatial memory can fade during long stretches of low stimulation. Textile motifs give the practice beauty and meaning.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Wayfinder's Horizon

Hold your course while the fleet drifts.

Five outrigger canoes cross a night ocean. Steer by the one in the center, even when the others point the other way.

Practices: Selective attention
Research model: Eriksen flanker task with congruent and incongruent trials
Cultural anchor: Pacific voyaging and wayfinding by stars and swells
Why it matters: The flanker task practices filtering out distraction. The reflection connects that skill to staying on your own course.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Wayfinder's Horizon

Dual Harmony

Two rules, one steady mind.

Cards appear in the garden or the court. In the garden, sort by symbol; in the court, sort by number. Switch smoothly as the card moves.

Practices: Cognitive flexibility
Research model: Task switching with measured switch cost
Cultural anchor: East Asian bamboo and chrysanthemum painting traditions
Why it matters: Moving between rules is a skill people who live between cultures use every day. The game frames adaptability as strength.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Dual Harmony

Jade & Vermilion

See the color, not the word.

Words appear in colored ink. Tap the ink color and let the word pass by, including heavy words like shame and duty in Level 2.

Practices: Inhibitory control
Research model: Stroop and emotional Stroop interference
Cultural anchor: Lacquer arts of China, Japan, Korea, Vietnam and Myanmar
Why it matters: Practicing a pause between seeing and reacting, with emotionally loaded words, gives players a safe place to rehearse letting heavy words pass.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Jade & Vermilion

Banyan Branches

Steady hands for many paths at once.

Dew drops flow down a banyan's branches. Flip the knots to guide each color to its bowl among the roots.

Practices: Divided attention
Research model: Multi-stream routing under rising load
Cultural anchor: The banyan as a tree of refuge across South and Southeast Asia
Why it matters: Several demands at once, met with small calm adjustments rather than panic: the practice and the lesson are the same.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Banyan Branches

Tea Ceremony Sequence

One step, held gently in mind.

Tea utensils appear one at a time on a wooden tray. Tap Match when an item repeats one step back, or two steps back in Level 2.

Practices: Working-memory updating
Research model: Adaptive 1-back and 2-back continuous recognition
Cultural anchor: Tea traditions of China, Japan, Korea, Taiwan and Vietnam
Why it matters: The n-back task is a standard working-memory exercise. The slow, ritual pace of tea practice keeps it calm and unhurried.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Tea Ceremony Sequence

Monsoon Canal

Plan the water before you open the gate.

Rotate canal tiles to carry water from the spring to every terrace field, then open the gate and watch it flow.

Practices: Planning and problem solving
Research model: Look-ahead puzzles with a limited move budget
Cultural anchor: Rice terraces of the Philippine Cordilleras and Yunnan's Hani terraces
Why it matters: Thinking several moves ahead is the same habit that supports planning for life after release.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Monsoon Canal

Kintsugi Reframe

Mend the crack with gold.

A broken bowl holds thoughts on each shard. Sort unkind thoughts from kind and true ones, then trace gold along the seams to see the thought reframed.

Practices: Reframing thoughts
Research model: Thought sorting grounded in cognitive-behavioral skills
Cultural anchor: Kintsugi, the Japanese art of repairing ceramics with gold
Why it matters: Learning to spot distorted thoughts, including shame carried for family, is a core coping skill. Repair becomes part of the story.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

Play Kintsugi Reframe

Spice Market Ledger

Count with confidence at the busy port.

Customers order cinnamon, cardamom and star anise. Work out totals and change, then remember running tabs across orders.

Practices: Everyday math and number memory
Research model: Mental arithmetic with working-memory load
Cultural anchor: Women merchants of the maritime spice ports: Malacca, Galle and Canton
Why it matters: Quick, confident everyday math supports budgeting and work after release.
Demo: Two levels, about 2 to 4 minutes each. Works offline.

How we talk about results

Research on brain training is clear on one point: people reliably get better at the exercises they practice. Whether that carries over to everyday life is less certain, and claims that games prevent illness or raise intelligence have been rejected by researchers and regulators.

So we make modest, checkable claims. The Lantern Suite offers structured practice in attention, memory, flexibility and planning. It is a pro-social activity with cultural and reflective content. It is not a medical device or a treatment, and it does not replace counseling or clinical care.

The strongest long-term evidence is for speed-of-processing training, which is why Saffron & Silk follows that research model closely.
