Today’s Lie
Inspiration
Deception has always fascinated people. From classic novels to modern TV dramas, stories built on lies, mystery, and hidden truths consistently capture attention. Even today, content centered around deception remains incredibly popular.
This inspired Today’s Lie — a social, daily game designed to spark interaction, curiosity, and debate among players.
What It Does
Today’s Lie is a monthly-driven daily game:
Submission Phase (Days 1–15)
- Players submit statements that could be either true or false
- Each valid submission ** costs 25 Bits** (in-game currency)
Review Phase (Days 16–30)
- Submissions for the next month are randomly selected (if not selected 25 bits is refunded to their accounts)
- Selected submissions are reviewed and prepared for gameplay
Daily Gameplay (Following Month)
- Each day, one submission is revealed
- Players vote whether it is a Lie or a Truth
Results & Rewards
- Results are revealed the next day
- Voting costs 3 Bits
- Correct vote → +10 Bits
- If the submitter fools the majority → +75 Bits
Leaderboard
- Players are ranked by total gains
- Purchased Bits do not affect leaderboard rankings
How We Built It
- Built using Reddit’s Devvit React template
- Integrated Redis for:
- Time-based logic
- Submission tracking
- Daily content rotation
- API safeguards ensure game rules are enforced
(e.g. submissions are blocked after the 15-day limit)
The game is fully automated and can run without developer intervention.
Challenges We Ran Into
- User profile pictures
We couldn’t find a reliable way to display Reddit user profile pictures inside the game. This is something we plan to solve in future updates.
Accomplishments We’re Proud Of
- Fully self-operating game lifecycle
- Fair and balanced reward system
- Reliable time-based logic using Redis
What We Learned
- Practical usage of Redis for state and time management
