Updated October 2026 with current Indian retail prices.
Circuit Sort: Screw Puzzle is a free screw sort puzzle for Android and iPhone, and for all of October it is running a Halloween high score cup. The Halloween Endless Cascade cup lives in the game’s Arcade mode, with its own leaderboard for the month.
The Halloween cup is open until 31 October 2026.
Circuit Sort is made by Brock Hall, a solo indie developer who publishes as OrehRuoy on Google Play. He told Gaming Nation the cup runs from 1 to 31 October, and the game agrees: the board is labelled OCT 2026 and, in the game’s words, resets every month.
WatchHow to join the Halloween Endless Cascade cup
Tap the pumpkin on the main menu to see the cup.
Play Arcade, the endless mode. It has its own button on the main menu.
Enter three initials when your run ends. Your best run of the month goes on the board.

In the game’s own words, only Arcade scores count, and your best run this month is listed with your three initials. The update that added Arcade says it is always unlocked, so you do not need to finish the campaign first.
Tips from the developer
- Watch the upcoming bins. The next colours are shown at the top of the board.
- Don’t fill a colour until you can clear it.
- Save your tools for the boards that jam.
- Stay calm in Arcade. The pace climbs every few clears.

Brock posted his own Daily Challenge clear on YouTube and asked players to beat it. Daily Challenge is one timed puzzle a day, with no undo and no power ups.

Each level is a circuit board held down by coloured screws. You unscrew them and drop each one into the bin of the same colour. The bins along the top show which colours come next, and a small reserve tray holds screws that have nowhere to go yet. Pick the wrong screw and the board can jam, so the order of your taps matters.
Besides Arcade, the App Store listing promises:
- a campaign of 175+ handmade levels
- a Daily Challenge, one timed puzzle a day with no undo and no power ups
- power tools (a drill, a hammer and a dust pan) for when a board gets stuck
- a Circuit World Cup leaderboard where you play for your country
The App Store lists 26 languages for the game (English and 25 more), and Hindi is one of them.
Made by one developer
Brock built Circuit Sort on his own, in the Godot 4 game engine, as he wrote when he announced the game. It came out on Google Play on 24 May 2026, and on the App Store two months later. His developer name has a small joke in it: OrehRuoy is YourHero spelled backwards, and his website shows the word YourHero faintly under the name.
It has not stood still since. The iPhone version alone has had ten updates since 22 July. The main moments, from launch to the Halloween cup:

He also answers players. In late August, a Google Play reviewer said the board was so dark that the screw colours were hard to tell apart. Eleven days later, Brock replied:
“I’ve added a lighter border to the darker screws so they should be easier to see now.”
