Shadowmatic

What the game is

Shadowmatic is a phone and tablet puzzle about shadows. A spotlight shines on one or two abstract objects hanging in mid-air, and their shadow falls on the wall behind. The objects look like nothing in particular. The shadow, at exactly one angle, looks like a bird, a teapot, a bicycle. Your job is to find that angle.

Triada Studio released it in 2015 and it won an Apple Design Award. The rooms are photoreal and lit like a gallery, with more than a hundred and thirty levels across fifteen themed environments, plus a separate Other Worlds chapter adding thirty more. There is no timer, no score and no failure, and an assistant button and hint system wait for when a level stops moving.

On the App Store it is a paid app, with one extra chapter sold separately. On Google Play it starts free and a single in-app purchase unlocks the rest. There is no reading anywhere in it, and it runs on phone, tablet and Apple TV.

What you actually do

You drag a finger across the screen and the object turns. The shadow smears into something unrecognizable, then almost into something, then past it. So the play is a slow hunt: rotate a little, watch the shadow rather than the object, and back up when the silhouette starts to break. Later levels hang two objects at once, so you are looking for the angle where both shadows overlap into one shape, and turning one ruins the other. Each room has a theme, so knowing this is the kitchen narrows what the shape can be. Extra silhouettes hide in most levels for anyone who keeps turning.

What it exercises

• Predicts what a three-dimensional object looks like from another angle
• Reads a two-dimensional projection back to the solid that made it
• Adjusts two linked variables toward a single target
• Uses a room's theme to narrow what a half-formed shape could be

Why we rate it Low Worksheet score 42 / 100

1. FitHow much real knowledge or skill does the play itself make you use?45weight 45%

   Fit scores 45. This is close to a single-skill game: mental rotation and projection are not practiced alongside the puzzle, they are the puzzle, with no scoring or story wrapped around them. It sits in the middle rather than higher because the hint system lets a stuck player skip the thinking entirely instead of working through it.

2. TransferWill what you practise here work outside the game?35weight 30%

   Transfer scores 35. Spatial skill is the area where training research is strongest generally, which is why the mechanic is worth taking seriously at all. But that research concerns spatial training broadly, not this app, and nobody has tested whether playing Shadowmatic itself moves anything. Treat it as pleasant practice in a valuable skill, not training with a known effect.

3. PracticeDoes the game make you use that skill again and again, as it gets harder?45weight 25%

   Practice scores 45. The content is finite and the puzzles do not regenerate: once a silhouette is found that level is finished for good, and a determined player reaches the end in a few sittings. The practice is intense while it lasts, which lifts it above the very bottom, but there is little reason to come back once the levels are done.

What the evidence says

Editorial onlyNobody outside our desk has checked this. It is our reading of how the game plays.

The evidence level is Editorial only. Triada Studio's own page and the App Store listing confirm the developer, the 2015 release, the platforms, the Apple Design Award, the level count across fifteen environments plus the Other Worlds chapter, the hint system, and the App Store rating of 4.8 from 2,095 ratings. A third entry, the Uttal and colleagues 2013 meta-analysis of spatial training, is listed for context only: it establishes that spatial skills respond to training in general and says nothing about this game specifically. It is not treated as evidence about Shadowmatic.
