Tandem Court Doubles

Four fixed people, two doubles teams, one complete compact set. Cover the net, target the open side and alternate service between both teammates. A serve must land diagonally in the service box; only the designated receiver may return it after a bounce. Later either partner can volley and the doubles alleys are in play. Flat shots and topspin change the flight and rebound.

First to four games wins, no-ad scoring at 40:40, and a 3:3 tie-break to seven with two clear points, capped at eleven. Two service faults lose the point, let repeats are bounded, and twelve seconds without a serve forfeits it. Fifteen minutes ends in a draw. Fixed court sides and a short set are explicit arcade rules.

Solo controls Blue1 with three labeled bots. Local2 gives one human per team plus a bot partner, with independent keyboard or touch docks. Local4 uses four disjoint key groups on a shared external keyboard; rollover depends on hardware. Online requires exactly four signed-in humans, two fixed roles per team, without bot seat filling. Practice ends after twelve points and counts actual Blue1 returns and target hits.

Aim and power sliders preview landing; a separate release prepares the stroke. Controls sit outside the court, resolution follows the usable display and actor size remains bounded on large monitors. Landscape is recommended; portrait works. English and Brazilian Portuguese help, original synthesized music and hit/bounce/score sounds, mute, solo/local pause and rematch.

Online uses the PixelJS relay with client-host authority. Results are casual and unverified; winners tie first and losers tie third. All four acknowledge the terminal score. Losing a connection or hiding the game ends the session. No reconnection or host migration.
