Paddle Rally

Rally the ball to prove you're human. Paddle Rally is a Pong-style Caputchin captcha built on the Phaser engine, one of the first-party Core Pack games. It ships two modes, chosen by the site owner:

• Rival (default): classic Pong against a CPU paddle, first to the target points. A deliberate flick of your paddle puts spin on the ball to out-skill the rival; a held key cannot.
• Solo: no rival. The right side is a wall; keep the ball alive and survive a target number of returns. The ball runs faster here, since there's no rival to outrun, so it's a pure reflex test.

How it plays

Rival: keep the ball in play and slip it past your rival's paddle to score. First to the target (three points by default) wins and clears the check; a sharp flick angles the ball where the rival isn't. After a win you can keep rallying in a relaxed endless mode that isn't scored.

Solo: the ball bounces off the right wall back to you; keep returning it. Survive the target number of returns (five by default) and you clear the check; miss once and you retry. The ball ranges the full court and speeds up, so it rewards tracking.

Customization

Site owners can tune Paddle Rally from the marketplace, no code required:

• Gameplay (configurations): mode (rival or solo), points to win / returns to survive, paddle speed, difficulty, and sound. Presets: default (rival), hardcore (rival), solo, solo-fast.
• Languages (locales): ships the full official language set (English plus ten more). Pick one, or let it follow the visitor's browser.
• Look (skins): court, paddle, and ball colors, in dark and light themes. Presets: default, night, sandlot.

Accessibility and support

• Keyboard: fully playable with the arrow keys (or W and S) and space.
• Touch: fully playable by dragging anywhere on a phone or tablet.
• Responsive: fills any container size and aspect ratio, portrait or landscape, with no letterboxing.
• Screen reader: the score and each serve are announced through a live region, and the play area carries a descriptive label. The announcer follows the active language and reading direction.
• Audio: optional. Short procedural blips mark the serve, paddle hits, and wall bounces; turn them off with the sound setting. Every cue is also shown on screen, so Paddle Rally is fully playable muted.

Security model

Paddle Rally is a skill check: it filters non-playing input, not all automation. Be clear-eyed about what that means. Both modes share the same posture.

• What it stops, by construction: a paddle that sits still or holds one direction never wins. In rival mode it imparts no flick, so its shots stay soft and the rival always returns them; in solo mode the ball ranges the full court, so a still paddle is always left behind. Non-playing input loses, in either mode.
• What it does not claim: Paddle Rally is not a Turing test. A program that genuinely tracks and returns the ball plays the way a person does and can pass, as it could for any skill-based challenge. A random/erratic bot can also luck through at a small, bounded rate (a few percent at the easiest settings, lower at the defaults). It is a probabilistic filter, not a proof.
• Where it fits: the game is one signal. Caputchin combines it with behavioral and server-side checks; it is never the sole line of defense.
• Why a win can't be forged: the verdict is recomputed by deterministic server-side replay of your recorded inputs, so the result cannot be faked in the browser.
