Watch the ruby. Remember the pattern. Play it back. RubyRepeat is a pure memory game played on a gleaming eight-facet gem. The board lights up one facet at a time and plays its tone — then it's your turn to repeat the sequence. Every level adds a note and picks up speed. One wrong tap, or one moment of hesitation too long, and it's game over. Simple to learn. Genuinely hard to master. TWO WAYS TO PLAY • Classic — the ruby in deep faceted reds, the way a gem should look • Color — every facet gets its own vivid hue for an extra visual anchor Switch modes mid-game without losing your score, level, or sequence. SHARP, SATISFYING PLAY • Eight facets, eight tones — sound and light reinforce your memory • Precise touch targets shaped exactly like the facets you see • Sequences grow from 4 notes to 20 as the pace quickens • Score climbs faster at higher levels: every correct tap is worth more CLEAN AND FOCUSED • Free, with no ads, no in-app purchases, and no account required • Nothing tracks you — your sound preference is the only thing saved • Check the global top 25 right in the app, and submit your best runs if you choose • Designed for iPhone and iPad How long a pattern can you hold in your head — 8 notes? 12? 20? There's one way to find out.
