Same-device multiplayer
Every game is designed for two or more people sharing one phone or tablet. Turn-taking and simultaneous touch are both first-class citizens.

The promise
Less setup.
More “your go”.
Friends, couples, families, and small groups should not need a controller, account, internet connection, or lengthy tutorial to play together. The first round normally starts after three decisions: choose a game, confirm players, start.
Design principles
Made for the bit
between plans.
Offline and private
Core play works in airplane mode. No accounts, cloud saves, chat, player profiles, scores, boards, or round payloads leave the device. Firebase lifecycle events use per-game names such as four_in_a_row_started and carry only the game_type value, plus an optional player_style_selected style-token signal. Firebase/Google SDKs may also collect standard app, device, install, diagnostic, and usage data under their disclosures.
Fast to understand
Short setup, clear ownership, visible feedback. Rules should be learned through one concise example or the first interaction.
Thoughtful by default
Native Android, Kotlin, and Jetpack Compose keep the experience responsive, adaptive, and at home on the hardware it runs on.
Under the hood
Simple on the surface.
Serious about the edges.
Each game has a plain Kotlin rules engine: immutable state, explicit actions, deterministic reducers, and tests for the tricky bits. The host owns setup, pause, results, replay, and restoration so players get one coherent journey even when the game changes.
That means fair rapid input, safe rotation and backgrounding, sensible back behaviour, and no mysterious “it depends” moments. The board fits the window. The next tap is never held hostage by an animation.
Phone smoke checks install a clearly labelled Cool 2 Player Vector Games (Smoke) build alongside the production app, so release data and installs stay untouched. The validated release source also produces signed Play Store bundle version code 17.
Latest release
The full shelf,
ready to ship.
Release builds now include every release-enabled game in version code 17, including Noughts & Crosses in both local versus and solo play, plus Hit the Mark, a simultaneous timing score race with a steeper block-and-target ramp and faster motion through level 25. The results-screen advert countdown still offers a contextual “Upgrade to Premium to skip adverts” link while adverts remain enabled. Kitchen Team stays in debug builds as its co-op polish continues, and feature profiles are archived by version code so each release keeps an auditable snapshot.
