8 problem solving games
Each game adapts its difficulty to you and scores every session.
Flow
Connect every pair of colored dots so the whole grid is filled and no lines cross.
Voltlock
Tap circuit cells to power them all down — each cell has its own toggle pattern.
Cairn
Swipe to slide and merge stones — reach the target tile before your move budget runs out.
Sluice
Slide barges along the canal — escort the numbered ones through the locks in their labelled order.
Slate
Fit the wooden blocks into the chalkboard silhouette. Rotations cost, and not every piece in the tray belongs.
Conduit
Lay pipe pieces fast to build a long glowing path before the racing charge catches up — the farther it flows, the higher you score.
Coil
Steer the light-serpent to swallow the glowing nodes in order — grow longer without coiling yourself shut.
Decant
Pour the glowing liquids between flasks until each flask holds a single colour — plan the pour order so no colour gets stranded.
How problem solving feeds your score
Behind every game is a per-skill rating that adjusts as you play. Your Problem Solving rating is one of six that roll up — by a fixed weighting — into a single Brain Fitness Index from 0 to 100.Problem Solving contributes roughly 15% of that number, so progress here moves your overall index.
