What Is PromptWars Virtual?

PromptWars Virtual is a recurring, online hackathon initiative organized by Hack2skill in collaboration with Google for Developers.

The central idea is to move beyond traditional, manual coding workflows and embrace intent-driven development. Participants describe what they want to build, use AI tools to accelerate development, and turn their ideas into working applications.

The event emphasizes practical implementation rather than ideas alone. Participants are expected to build functional applications that address real-world problems and submit their code along with a live application preview and a written account of their development journey.

Unlike an in-person hackathon, PromptWars Virtual allows participants to build and submit projects remotely.

Here is what makes the initiative worth exploring:

AI-powered development: Build applications using Google Antigravity and AI-assisted workflows.
Real-world problem solving: Work on industry-inspired challenges across different domains.
Recurring opportunities: Participate in multiple challenges throughout the year.
Build in Public: Document your process and share your learning with the developer community.
Leaderboard recognition: Compete with other participants and improve your standing.
Developer rewards: Earn Prompt Credits and redeem eligible rewards through the swag store.
Portfolio development: Build a collection of practical applications and technical write-ups.

Who Can Participate?

PromptWars Virtual is designed for a broad range of builders. According to the event overview, the initiative welcomes participants across three main groups.

1. Student Developers

Students can use the challenges to gain practical experience beyond classroom assignments and tutorials. Building applications around real-world problem statements can help develop problem-solving skills, improve project portfolios, and demonstrate familiarity with AI-powered development.

2. Professional Developers

Experienced developers can explore AI-native workflows, experiment with faster prototyping, and investigate how AI tools can support application development and implementation.

3. Indie Developers and Enthusiasts

Independent builders and technology enthusiasts can turn their ideas into working prototypes without necessarily relying on traditional development workflows for every task.

The event is intended for participants in India. However, registration alone should not be treated as confirmation of selection, as the organizers reserve the right to invite, shortlist, and confirm participants according to their selection process.

How Does PromptWars Virtual Work?

PromptWars Virtual follows a recurring challenge format, with each challenge providing a problem statement and a defined submission period.

The overall process is organized into four phases: challenge release, building, submission, and evaluation.

Phase 1: Challenge Release

A new problem statement introduces the theme and objective of the challenge.

The problems are designed around practical, industry-inspired use cases and may be categorized into different difficulty levels, including:

Beginner
Intermediate
Advanced

Each challenge gives participants an opportunity to explore a specific domain, identify a problem, and develop an application that addresses the requirements.

The event's introductory and problem statement explainer sessions help participants understand the challenge before starting development.

Phase 2: Building Phase

This is where participants turn their ideas into working applications.

Participants are expected to use Google Antigravity, the AI-powered development environment required by the event, to build their solutions. Other AI tools may complement the workflow, but using Google Antigravity is a stated requirement for submissions.

During development, participants should focus on:

Understanding the problem statement and identifying the intended users.
Planning the application's features and user experience.
Using AI-assisted development to implement the required functionality.
Testing the application and correcting errors.
Improving the interface, usability, and reliability.
Deploying the application so that evaluators can access a live preview.

The objective is not simply to produce an attractive interface. A strong submission should demonstrate a working solution that addresses the actual problem.

Phase 3: Submission Phase

Participants must submit two essential components to qualify for evaluation.

1. Technical Submission

The technical component includes the project code and a live preview of the application.

Your submission should make it possible for evaluators to understand what you built, inspect the implementation, and try the application.

Before submitting, ensure that the project runs correctly, the live link is accessible, and the core features work as intended.

2. Narrative Submission

The second component is a written account of your development journey, typically shared as a LinkedIn post or article.

This is the Build-in-Public aspect of the competition. It gives participants an opportunity to explain how they approached the problem, used AI tools, made technical decisions, and developed their solution.

A useful narrative can cover:

The original problem and why it matters.
The idea behind the proposed solution.
The tools and technologies used.
How Google Antigravity supported the development process.
Important implementation decisions and challenges.
The final application's key features.
Lessons learned and possible future improvements.

Both components matter. A working application without the required narrative, or a narrative without the technical submission, may not satisfy the dual-submission requirement.

Always follow the active challenge's official instructions for the exact submission deadline and format.

Phase 4: Evaluation and Announcement

After the submission period closes, the organizers review eligible entries.

Valid submissions can progress on the challenge leaderboard according to the competition's evaluation process.

The event is intended to reward practical implementation, creativity, problem-solving, and consistent participation. Participants should consult the official challenge guidelines for the applicable evaluation criteria and eligibility requirements.

The evaluation phase also gives builders an opportunity to learn from their work, improve their development approach, and prepare for future challenges.

Introductory Sessions and Problem Statement Explainers

PromptWars Virtual is not limited to releasing a problem statement and leaving participants to figure everything out independently.

The initiative also features introductory and problem statement explainer sessions. These sessions help participants understand the industry context, clarify the challenge requirements, and learn from AI engineers and other experts.

The event information describes live explainer sessions associated with the challenge cycle, along with recordings for people who cannot attend live.

These resources can be useful for beginners who need help understanding the problem, as well as experienced developers looking for additional context before choosing an implementation strategy.

You can explore the published session recordings and event updates through the official PromptWars Virtual website.

Prompt Credits: How the Reward System Works

One of the key incentives in PromptWars Virtual is its Prompt Credits system.

Prompt Credits are digital credits that eligible participants can accumulate and redeem for merchandise through the Hack2skill swag store.

The reward process works in four steps.

Step 1: Join the Challenge

Step 2: Build and Submit Your Application

Develop a functional application using the required tools and submit both the technical project and the written narrative.

Step 3: Earn Prompt Credits

According to the published event information, participants finishing within the top 400 positions in a challenge can earn Prompt Credits. The number of credits depends on the applicable reward structure and leaderboard position.

Step 4: Redeem Credits for Swags

Use your accumulated Prompt Credits to redeem eligible merchandise available through the official swag store, subject to availability and the store's redemption conditions.

The important distinction is that Prompt Credits are not the same as a guaranteed physical prize. They are redeemable digital credits, and the items available for redemption depend on the store's current catalog and applicable conditions.

What Swags and Rewards Can You Earn?

The event combines leaderboard recognition, digital credits, developer merchandise, and rewards for consistent participation.

1. Developer Swags Through the Swag Store

Eligible participants can use their Prompt Credits to redeem merchandise listed in the Hack2skill swag store.

The catalog is the place to explore the products currently available for redemption. Items, credit requirements, and stock may change, so check the live store before planning a redemption.

2. Virtual Credits for Top Finishers

The published event information also mentions Virtual Credits for the top 50 finishers in each challenge.

These credits are part of the event's reward structure. Refer to the official rules for the applicable conditions and redemption details.

3. Rewards for Consistent Participation

PromptWars Virtual also highlights additional Prompt Credit rewards for participants who maintain strong results across consecutive challenges.

The published reward structure includes the following opportunities:

4,000 Prompt Credits: For the top five Instagram Reels per challenge.
25,000 Prompt Credits: For participants finishing in the top 50 for three consecutive challenges.
125,000 Prompt Credits: For participants finishing in the top 50 for ten consecutive challenges.
1,500 Prompt Credits: For the top three women developers per challenge.

These rewards are subject to the event's eligibility requirements and official rules. Check the current challenge announcements to confirm the applicable conditions.

The consistency-based rewards encourage participants to keep building and submitting rather than treating each challenge as an isolated event.

4. Cumulative Leaderboard Recognition

PromptWars Virtual also features a cumulative leaderboard that recognizes continued participation and performance across multiple challenges.

A strong individual submission can help you compete in a particular challenge, while consistent results can contribute to your standing across the wider initiative.

For developers, this offers an opportunity to build a visible record of projects, experimentation, and participation.

Important: Prompt Credits Expiry

The event information states that Prompt Credits expire on 1 January 2027.
