Games
Chess
Play Biasa, an engine that blunders like a person on low levels and plays like a master on high ones. Then Stockfish reviews every move.
For two players
Backgammon & Nardy
Long nardy and classic backgammon against a bot or a friend on one screen. Fair dice, hints, matches to seven.
For two players
Checkers
Russian 8×8 and international 10×10 draughts against a bot or a friend. Flying kings, capture chains, full rules.
For two players
Biatrix + Zen Mode
Stack the falling blocks, clear the lines, lose track of time. Classic play plus a calm endless Zen mode.
Snake Classic
Guide your snake to eat colorful treats and grow. Walls are magical portals, but be careful not to bite your own tail!
Neuro Shift
Trains Spatial Working Memory and Mental Rotation. This specific exercise builds powerful new neural pathways and protects cognitive health.
Zen Blocks
A relaxing puzzle experience. Match and clear blocks in pure zen.
BiaPong
Table tennis on a single phone. Slide anywhere in your half and the paddle follows your thumb. Play solo, or lay the phone flat between two people — the far score is printed upside down on purpose.
For two players
Karma Swarm
A cosmic shooter where every shot has a consequence. Fifty waves of materialised karma, and balance counts for more than the score.
Best on a computer
2048
Slide the tiles, merge matching numbers, chase 2048. Simple rules, and always one more try.

Happy Cloud
Drift through the infinite sky in a state of pure relaxation. A mindful journey.
Best on a computer
Smile
A quiet reminder to soften your face and breathe. A small practice with a warm effect.
Body
Focus Timer
Work in focused blocks, then actually move. Short exercises between sessions, water reminders and an evening wind-down.
BiaSleep
A strike of the Genta bell every 36 seconds, fading into silence. A quiet way down into sleep.
Calm
Genta Chanting
The sound of the Balinese Genta bell was recorded in Bali using professional equipment.
Glince Synth
Light-and-sound synthesizer with eight worlds: tunnels, kaleidoscopes, fractals, a water pond and more.
Angel
A slow flight of light through the stars. Nothing to do — just watch and let the breath settle.
Lotus
A quiet pond that blooms as you breathe. Touch a bud, take eight calm breaths, and a flower opens with one bright thought.
Bia
A tiny pixel friend and a kind diary. Pet her, tap her, tell her about your day — her own little neural network feels the mood and answers warmly.

Good to know
Is everything on biasa.my.id really free?
Yes. Every tool and game here is free to use, with no ads, no accounts and no paid tiers. There is a small Say Thanks page for anyone who wants to support the work, but nothing on the site is ever locked behind it.
Do my photos or files get uploaded anywhere?
No. The apps run entirely inside your browser, so images, PDFs, text and audio are processed on your own device and never sent to a server. Most tools keep working even if you go offline after the page has loaded.
Do I need to install anything or create an account?
No. You open a link and it works. Preferences such as your chosen language or a game's high score are stored in your browser's local storage, and you can clear them at any time.
Which languages does the site support?
English, Indonesian and Russian. The language is detected automatically and remembered, and you can also force it by adding ?lang=en, ?lang=id or ?lang=ru to the address.
Who makes these tools?
One person: edo biasa, an independent developer and photographer living in Bali. Every app here started as something needed personally, then was cleaned up and shared.
