Real time
The server handles hundreds of comments a minute and puts them into the game before a player can put the phone down.

A game engine
for live broadcast
Kvízákov is not a show or a channel. It is software I wrote from scratch: it reads the live event stream from TikTok Live, scores the answers of thousands of viewers in real time and renders a game the whole chat plays at once.
- In public production
- 1,000+ hours live
- Proprietary technology
What it is
A broadcast that behaves like a game
An ordinary livestream is one directional: the host talks, the viewer watches. Kvízákov inverts that relationship. Every chat comment is a game input, every like is a scoring bonus, and every gift fires an effect the whole stream can see. Within two seconds of joining, a viewer becomes a player with a name, an avatar and a place on the leaderboard, with no install, no registration and no click outside TikTok.
Underneath sits a Python server holding the game state and a browser rendering layer whose output goes into the broadcast. A WebSocket runs between them. The whole chain from typing a comment to seeing your vote on screen takes a fraction of a second, otherwise the game would not work at all.
Proprietary content
A database of 90,018 questions across 230 topics and five difficulty levels. Every question is read out loud by the game.
Proprietary graphics
Fireworks, screen quakes, a music visualiser and a colour scheme driven by the real elevation of the sun.
Product in action
One round from start to finish
It opens with video straight from a broadcast, followed by screenshots in the order a player meets them during a game. Everything here comes from live production, nothing is staged.
Gameplay video
The best demo is the live one. You can find the game on the TikTok channel @kvizakov, where we broadcast almost every day in the afternoon and evening.
How it works
The journey of one comment
From the moment a player types a letter to the moment they see their avatar on screen, the input passes through four layers.
Layer 1
Event ingest
A client connected to the TikTok Live event stream receives comments, likes, gifts, joins and fan club memberships. Events arrive asynchronously and in bursts, so the input queue has to survive spikes without dropping a single vote.
Layer 2
Game server
A Python service holds the entire game state: the current question, the votes, gift stakes, streaks, multipliers, the treasure chest and the leaderboards. It also drives round timing and topic selection from the question database.
Layer 3
Rendering layer
A browser connected over WebSocket receives state changes and paints them onto a canvas. Heavy effects such as fireworks run in a dedicated Web Worker so the main thread keeps a steady frame rate even when chat traffic peaks.
Layer 4
Broadcast
The output of the rendering layer goes into the streaming software and from there back out to viewers. The loop closes: a player sees their own input as part of the show they are watching.
What the engine does
Key features
Everything below is finished and runs in every broadcast.
Answer recognition
The game accepts a letter or the full answer typed out in words. The text variant is matched tolerantly against typos and diacritics, and rewards the player with twenty times the base score.
Points economy
A base score, bonuses for likes, speed, streaks and fan club level, then a multiplier for the question level. Gifts convert into stakes that either return with interest or fall into a shared treasure chest.
Magic gifts
Six selected gifts work like game cards: sponsor of the day, treasure chest activation, an all day streak, a half hour multiplier for the whole chat, a bonus for everyone and a topic pick.
Leaderboards and history
Running standings, daily, weekly and monthly boards, a crown for the biggest gifter of the day and persistent player statistics across broadcasts.
Question narration
Every question and answer is converted to speech, so the game can be played by ear. The voice is synchronised with the round timer.
Live visual layer
Fireworks carrying the gifter's avatar, screen shakes on large gifts, a music visualiser reacting to the audio and a colour scheme driven by the real elevation of the sun over Czechia.
Technology
What it is built on
No framework scaffolding. Server logic in Python, rendering in vanilla JavaScript on a canvas, a WebSocket in between. Owning the code gives me control over every frame, which matters when a broadcast runs six hours straight.

Business model
How Kvízákov makes money
One revenue stream today, a second one ahead that does not depend on a single channel or a single platform.
Virtual gifts during the broadcast
Viewers send virtual gifts during the game, and TikTok shares their value with the broadcaster. In Kvízákov every gift has a game effect: it converts into a points stake, and selected gifts act as spells that change the whole stream.
That connection is exactly why gifts do not go unnoticed here. The viewer gets a gameplay advantage and a visible tribute on screen rather than a thank you.
Licensing the engine
The engine is written so that it is not tied to one channel. Questions, language, graphics and rules are separated from the game core. The goal is to offer it to other creators, brands and media companies as a finished product for their own interactive broadcasts.
The model is a subscription for running an instance plus a share of broadcast revenue. That turns a single show into a tool capable of running on hundreds of channels at once.
Why quizzes. A knowledge game is the one format that works regardless of the age of the audience, localises by swapping the question database, and naturally brings players back daily. The engine itself is not tied to quizzes.
