How to play

Rogue step buttons have escaped the sequencer and march down four lanes, one row per beat. You ride the big step buttons at the bottom with a knob-cannon, and you may only fire on the quarter note. Count along and pull the trigger on the beat. Press FULLSCREEN (or the F key) to play on the whole screen; on a phone, hold it upright.

Every level is a different beat. You play through a setlist of the nine artist presets from the online TR-808, each at the tempo the artist programmed it: T/Error (120 BPM), Nachtwald (128), Anthony Rother, Carl Finlow, Cliff Dalton and The Exaltics (130), Legowelt and The Droid (135), and Lloyd Stellar closes the set at 140. Each level opens with the artist's photo and a few bars of the full groove, so you know what you are defending, and the bio appears below the machine. Clear all nine and the set starts again, 8 percent faster.

The buttons march in the rhythm of the pattern itself. A kick sends a red button, a snare an orange one, hats and shakers a yellow one, and claps, rims, toms and cowbell a white one. Once you know the beat, you know where the next button lands.

  • Red buttons are kicks, orange are snares, yellow are hats and white are cowbells. Shooting one plays its 808 sound
  • PERFECT shot (within 75 ms of the beat at 118 BPM): 100 points x multiplier
  • GOOD shot (within 145 ms at 118 BPM): 40 points x multiplier
  • Timing windows shrink with the tempo: they stay the same fraction of the beat, so a higher BPM gives you fewer milliseconds and fast patterns are as strict as slow ones
  • Blinking accent buttons: double points. From level 2 most of them are armoured: a GOOD shot cracks the plate, a PERFECT shot goes straight through
  • Fast buttons (two chevrons): from level 3 some buttons hop on the eighth note and reach you twice as fast. Worth 50 percent extra
  • Combo: every 4 on-beat kills raises your multiplier and unmutes a layer of the groove: hats, shakers, claps, then the full pattern
  • Off-beat shot: your cannon jams, the combo resets and the groove strips back down
  • Fuses: a button reaching the bottom blows one of your four fuses. Lose all four and it's game over. Every third level repairs one
  • Level bonus: 250 points times the level for clearing it, plus 500 times the level if no fuse blew

Every level sends more buttons, closer together. The first set runs from 120 to 140 BPM, the second 8 percent faster, and so on with no limit. A top 10 score puts your name in the hall of fame below. The board was reset on October 3, 2026, when the setlist version of the game went live.

Every sound comes from the 808

This site already has a free online TR-808 drum machine, and every drum sound in this game comes straight from it: the same tape-saturated kick, snare, hats and cowbell samples, untouched. The backing beats are the real artist presets from that drum machine (T/Error, Nachtwald, Anthony Rother, Carl Finlow, Cliff Dalton, The Exaltics, Legowelt, The Droid and Lloyd Stellar), played back step for step with the same lookahead scheduling the 808 itself uses. Since October 3, 2026 the game plays them as a setlist, one pattern per level, and the hits in each pattern decide where the buttons spawn.

The lane colours come from the machine too. Red, orange, yellow and white are the four colour groups of the sixteen step buttons on the original Roland TR-808 from 1980, the drum machine behind electro, Miami bass and a lot of hip hop. Here those buttons fight back, and you stop them by becoming the metronome.

If you play well, you are mixing the track. Every four-hit combo unmutes another layer of the pattern, from a bare kick and snare up to the full groove with toms and percussion. Miss the beat and the mix strips back down.
