A quick round. A score to beat.

The problem

I started with the idea of an Olympics-style competition for everyday people, played in a browser. It needed games you could learn quickly on a keyboard, mouse or phone, with a score worth coming back to beat.

What I built

I built a basketball shooting game, an archery game and a rhythm sprint, with a shared home, difficulty choices and settings. Each sport has its own game rules and Canvas artwork. Challenge codes let friends play the same setup.

1. 01

   Choose

   Pick a sport and difficulty, or open a friend's challenge code.

2. 02

   Play

   Aim a shot, release an arrow or find a running rhythm with the game's controls.

3. 03

   Try again

   Check the score, beat your local best or share the same setup with a friend.

What I had to get right

1. Keep the rules separate from the drawing

   The basketball simulation advances in fixed steps. Canvas draws its state separately, so drawing more frames does not give a shot different rules.

2. Give friends the same setup

   Challenge codes preserve the sport and difficulty. Basketball and archery also recreate the same course from a seed. Invalid codes are rejected before play.

3. Make the small details feel connected

   I built the athletes, scorecards and sound into the same visual style. Music and effects have separate controls, and saved preferences carry between games.

How I check it

• Game-rule tests cover scoring and repeatable basketball shots.
• Challenge and storage tests cover invalid codes, saved preferences and unavailable browser storage.
• Browser tests cover keyboard controls and audio behaviour when a page is paused or hidden.

The result

The first three games are live, with personal bests, replayable challenges and shareable scorecards. I’m still developing Oddletics and plan to add more sports.
