Duel Echo
Read full descriptionHide full description
Duel Echo is part of the Duel series — games built around one idea: your phone as a board game. Two people, same room, one device between them. No online mode, no matchmaking, no notifications. Just the game and whoever's sitting across from you. OBJECTIVE Each player gets a glowing disc of musical pads on their half of the screen. Watch, listen, memorize — then play the melody back, note for note. One wrong tap and the point goes to your opponent. First to the target score wins. TWO WAYS TO DUEL • Classic — the game composes a unique melody for each player and adds a note every round. Both of you fight your own growing sequence; the first memory to crack loses the round. • Chain — you build the melody together. Repeat everything your opponent played, then add one note of your own. The tune keeps growing until someone's memory gives out. THE REPEAT LIFELINE Blanked out mid-sequence? Once per turn you can replay the melody — but only once. Spend it wisely. MAKE IT YOURS • 7 instruments — piano, guitar, marimba, xylophone, voice, organic, and a festive X-mas set • 4 to 8 pads — more pads, more notes, more ways to slip up • 5 tempos, from a mellow Largo to a merciless Presto • Colour-off mode — all pads turn grey and only light up during playback. For players with something to prove. • Match length — first to 3, 5, 7, 10 or 20 points • Custom player names, light and dark themes BRAG-WORTHY STATS The game tracks flawless streaks for both players and crowns the longest melody survived — so the winner has numbers to back up the trash talk. EASY TO START A short illustrated tutorial gets both players going in under a minute. If you've ever repeated a blinking pattern on a toy from the 80s, you already know how to play. CLEAN & FOCUSED No ads. No accounts. No internet required. Pick it up and play. --- A musical memory duel with glowing discs, real instrument sounds and a smooth touch interface. Part of the Duel series — turning phones back into board games.
