"Rolls" (as introduced in In the Groove 2), which appear to be spiky, green and yellow holds, must be rapidly tapped (like a drumroll, hence the name) for them to count.

All machines will immediately fail any player who stops hitting arrows long enough to accrue 30 misses in a row.

However, if the player utilizes a USB card to keep track of their scores, their combo will also carry over from one credit to the next.

The game has safety nets for players on easy difficulties that allows them to play all of the songs on their credit without failing out.

Kyle Ward (also known as KaW, Inspector K, Banzai, E-Racer, and Smiley) is the developer's house musician, who composed many of the songs.

[10] The PS2 version contains the Novice mode carried over from In the Groove 2, Liquid Moon as a fully playable track, and 4 songs from the sequel.

A PC version was released on August 16, 2006, featuring 3 songs from the now-canceled In the Groove 3,[11] widescreen aspect ratio support, and Edit Mode.

On October 18, 2006, Roxor announced that Konami had acquired the intellectual property rights to the In the Groove series as part of the settlement to this litigation.

In the Groove is built on a complete PC system dubbed the "Boxor" which runs a heavily modified version of the Debian Linux distribution.

The computer contains a standard IDE hard disk (usually 40gb or 80gb in size), single-core 32-bit processor (Usually AMD Athlon or Intel Celeron), 128mb nVidia GeForce FX 5200 graphics card, 256MB or 512MB of DDR RAM, a Gigabyte Technology GA-8IPE1000 Pro2 motherboard, and a USB 2.0 hub (Cypress EZ-USB FX2) for transferring user statistics and edits onto a flash drive.

The software used to run the game is a proprietary fork of the open source StepMania computer program.

Anti-piracy measures are achieved through the use of a "serial dongle" which prevents execution of the software on an unlicensed computer.

This is typically done by removing the power cord and CMOS battery, then activating CMOS_PWD reset jumper on the motherboard of the computer.
