Spark

Volt's first game: a calm wire puzzle where you turn tiles to carry power from batteries to bulbs, and every solved level lights a window in a small town.

The Challenge

Most puzzle games run on timers, lives, and ads that break in every few levels. They are built to rush people, not to give them a quiet few minutes.

The game needed to teach itself in a few taps, stay calm all the way to its hardest boards, and play just as well with a TV remote as with a finger on a phone.

What We Built

Spark is one of Volt's own products, built and run in house rather than for a client. Volt built it with the Godot engine, so one game and one remote friendly design carry across phones, computers, and TVs.

Turn the Tiles

PLAY

Tap a tile to turn it. When a wire carries power from a battery to a bulb, the bulb glows. Yellow bulbs need yellow, blue bulbs need blue, and green bulbs need both at once.

The Town and the Daily Puzzle

TOWN

Every solved level lights a window in town, ten to a street, while the boards grow from 3x3 to 7x9. A daily puzzle, the same board for everyone, waits each day. No timers, no lives, and no ads.

On the TV

TV

The same game on a television, played with the arrows and OK on the remote. The tile in focus is always outlined, so it is clear what the next press will turn.

The Outcome

Spark gives people a calm puzzle to come back to every day. The first 42 levels and the daily puzzle are free, and a monthly Spark Premium opens the rest of the town. It is live in the Microsoft Store, with Google Play for phones and Android TV, Amazon Fire TV, LG, Samsung, Roku, Titan OS, and Whale OS coming.
