REVIEW
Wrench Puzzle turns the nut-and-bolt fad into a passable webOS time-killer.
Mobile Joypad's free mechanical-puzzle game lands on LG TVs as a remote-friendly take on the unscrew-and-sort genre that flooded phones in 2024.

Wrench Puzzle is a screw-sorting game on a 55-inch screen — exactly as strange and exactly as oddly soothing as that sounds. The nut-and-bolt puzzle genre had its viral moment on mobile in 2024, when seemingly every casual studio shipped a near-identical app where you unscrew coloured bolts off stacked plates and re-thread them until each plate is single-colour. Mobile Joypad’s webOS port lifts that loop wholesale and sets it on the living-room TV.
The translation is more graceful than it has any right to be. Bolt-sorting is a slow, stationary, eyes-on-the-board activity, which is the rare casual-game profile that survives the jump from a handheld touchscreen to a Magic Remote pointer ten feet away. The boards read clearly, the unscrew animation is satisfying, and the level grid is long enough that you won’t run out of puzzles before you run out of patience for the genre.
What you’re getting is a competent port of a derivative game. That’s not a recommendation against — free, low-pressure, and visually legible is a sensible niche for a webOS game in 2026 — but it’s an honest description. Wrench Puzzle isn’t reinventing the nut-and-bolt formula. It’s just bringing it, intact, to a screen most of these games never bothered with.

FEATURES
Wrench Puzzle is a mechanical-puzzle game in the nut-and-bolt sorting genre that overran mobile app stores in 2024 — boards are populated with coloured bolts threaded through stacked plates, and the task is to unscrew bolts and re-thread them so each plate ends up holding a single colour. Clear the board, advance the level.
The webOS build presents the same loop on a TV. Levels are picked from a scrolling grid, the cursor is driven by Magic Remote pointing or directional input, and a tap of the OK button unscrews the highlighted bolt. Free play with no time pressure; the difficulty curve is paced by adding bolt colours and extra plate layers rather than a clock.
Free to download. The standard genre monetization pattern — rewarded video ads for hints or board resets, with an optional one-tap purchase to remove ads — is the obvious revenue model, though the in-app commerce flow on LG TVs is the usual TV-store detour rather than a single tap.
MISSION ACCOMPLISHED
The genre translates to a TV better than most casual phone games do. Bolt-sorting is a stationary, low-tempo activity that doesn't suffer from the latency of pointing-at-a-screen-across-the-room, and the visual logic — bolts, plates, colours — reads cleanly at couch distance.
Mobile Joypad has shipped enough webOS titles to have the basics right: the Magic Remote pointer is responsive, the level grid scrolls without stutter, and the colour palette is loud enough to stay legible on a TV from any angle.
ROOM TO IMPROVE
This is a derivative game in a derivative genre. The original wave of nut-and-bolt puzzlers on mobile in 2024 produced dozens of near-identical clones, and Wrench Puzzle doesn't try to differentiate beyond competent execution. There's no meta-progression to speak of, no level editor, no daily challenge — just a long ladder of increasingly busy boards.
Free-to-play monetization on TVs is also still awkward. Ad breaks are tolerable on a phone you're already holding; on a TV, an interstitial video that requires a remote click to dismiss is a friction the genre's mobile origins didn't have to design around.
CONCLUSION
Wrench Puzzle is a fine free download for an LG TV owner who wants a low-stakes puzzle to play while half-watching something else. It is not a destination game and it is not trying to be one. If the nut-and-bolt fad already passed you by on mobile, this won't convert you; if you enjoyed the genre on a phone, the webOS version is a credible second screen for it.
