Game Overview
Pill Roulette, also known as Side Effects, is a tense, turn-based game where players engage in a high-stakes medical trial, gambling with their virtual lives by consuming pills with unknown and potentially lethal consequences [28].
"The game presents a darkly humorous and dangerously addictive experience, inviting players into a deadly experiment where only one test subject is intended to survive."
Each round, players face a selection of pills, some beneficial (healing, tactical advantages) while others can be harmful (damage, negative status effects, or instant death) [2]. The core revolves around managing uncertainty and making critical decisions under pressure, as pill effects remain mysterious until consumed.
Core Game Objective
The primary objective is to survive longer than your opponent by managing your health and strategically navigating the unknown effects of various pills [4]. Players must monitor both their direct health pool and their body's resistance – a crucial secondary statistic that decreases with each pill consumed.
Key Mechanics
- Unknown pill effects
- Health & resistance management
- Item shop between rounds
- Psychological tension
Risk Factors
- Instant death pills
- Increasing tolerance
- Opponent bluffing
- Time pressure
Game Rules & Basic Gameplay
Turn Structure & Core Mechanics
The game follows a fundamentally turn-based structure where players alternate taking actions, primarily choosing and consuming pills [2]. Each round presents a selection of pills with completely unknown effects until consumed.
Turn Sequence:
- Pill Selection: Choose one pill from the available options
- Consumption: Ingest the pill and reveal its effect
- Effect Application: Impact on health, resistance, or status
- Item Phase: Use items from your inventory (optional)
- Turn End: Pass to opponent and prepare for next round
The Resistance System
The resistance system is a crucial mechanic that significantly impacts gameplay and strategy. As stated in the Steam description: "Every pill impacts your resistance. Manage it wisely: zero resistance means death" [51].
Resistance Effects
- Decreases with each pill consumed
- Risk increases as resistance drops
- Zero resistance = instant death
Strategic Implications
- Risk-reward assessment changes
- Long-term planning required
- Item usage timing becomes critical
Victory Conditions
Victory is achieved by outlasting your opponent. The game continues until one player's health or resistance reaches zero, resulting in their elimination from the medical trial [25].
"Only one leaves" - The game's tagline perfectly captures the brutal survival-horror theme

In-Game Items & Pill Effects
9 Unique Items
The Steam version features 9 unique items accessible through an in-game shop between rounds. These "experimental goodies" can shift the odds in your favor [28].
Candy
Allows safe turn skipping - useful for avoiding risky pills or forcing opponents to take more turns.
Vaccine
Recovers lost health/resistance - crucial for sustaining longevity and timing.
Antidote
Neutralizes poison effects - specific counter to poison-inducing pills.
Mouth Clamp
Likely prevents pill consumption or its negative effects - defensive utility.
6 Pill Types
The game features 6 distinct pill types with completely unpredictable effects until consumed. Each choice is a significant risk with potential for healing, harm, or special effects [271].
Helpful Pills
Provide positive benefits - restore health/resistance, grant temporary buffs, offer resources.
Harmful Pills
Cause negative consequences - deal damage, inflict poison/debuffs, reduce resistance.
Lethal Pills
Can lead to instant death - extreme risk, especially when resistance is low.
Special Effects
Unpredictable outcomes - temporary powers, complex debuffs, game-altering effects.
Strategic Item Usage
Timing
Don't hoard items too long, but avoid frivolous use. Consider game state and opponent's position.
Psychology
Holding powerful items creates uncertainty. Revealing items can force opponent strategy changes.
Synergy
Combine items with pill effects - boost positives or nullify negatives for maximum impact.
Advanced Strategies & Tips
Managing Resistance Effectively
Effective resistance management is arguably the most critical skill in Side Effects. Since reaching zero resistance means death, maintaining this vital stat is paramount [393].
Avoid Over-Reliance
Don't depend too heavily on a single pill type. Diversify consumption to mitigate tolerance buildup.
Risk Assessment
High resistance allows risk-taking. Low resistance demands caution and safe options.
Track Patterns
Monitor how different pills affect resistance and watch for delayed consequences.
Strategic Item Usage
Items are powerful but scarce resources that can dramatically alter the game's course. Both players have access to the same tools, creating a dynamic interplay of prediction and counter-play.
Optimal Timing
Use healing items preventively rather than as last-ditch efforts. Save defensive items for critical moments.
Psychological Play
Hold powerful items to create uncertainty. Reveal strategically to influence opponent choices.
Synergistic Combos
Combine items with pill effects - use boost items after beneficial pills, nullifiers before risky ones.
General Survival Tips
Learn Constantly
Analyze every round - pill effects, item impacts, opponent behavior patterns.
Manage Risk
Take calculated risks when healthy. Avoid unnecessary gambles when on the brink.
Balance Time
Consider long-term impacts over short-term gains. Toxicity increases with each pill.
Stay Calm
Don't panic under pressure. Take time to think through options in critical situations.
Opponent Psychology
Reading Opponents
- Observe risk tolerance and pill choice patterns
- Watch for hesitation or confidence in selections
- Gauge resistance levels through behavior
Psychological Warfare
- Use bluffing and misdirection techniques
- Anticipate item purchases and prepare counters
- Force opponents into unfavorable positions

Appendix: Original Card Game Rules
This section details the original "Side Effects" card game by Pillbox Games, which provides valuable context for understanding the digital adaptation's foundations [6].
Card Game Objective & Setup
Objective
Players start with unique "Disorder" cards in their "Psyche" and must treat all disorders using Drug cards [5].
Setup
- Deal 4 Disorder cards per player (2-5 players) or 3 (6+ players)
- Deal 4 cards face-down to each player's hand
- No duplicate Disorders in Psyche
Card Types & Functions
Disorder
Psychological ailments to treat. Each lists punishment triggered by Episodes.
Drug
Primary treatment method. Lists "MAY CAUSE" side effects (other Disorders).
Therapy
Wild card for treating Disorders, with specific exceptions for certain conditions.

Card Game Strategies
Understand Punishments
Prioritize treating Disorders with harsh punishments to avoid devastating Episode attacks.
Beware of Madness
The "Madness" Disorder forces discarding all Drugs - treat it carefully but don't ignore other Disorders.
Hoard Wisely
Avoid unnecessary hoarding as many effects force card loss. Strategic retention is better than indiscriminate collection.
Block Opponents
Hold cards opponents need for their critical Disorders to slow their progress and gain competitive advantage.
Plan for Vulnerabilities
Consider Drug side effects before playing them - understand what new Disorders you might become susceptible to.
Negotiate (Optional)
If using bargaining rules, leverage trades and deals to gain advantages through social negotiation.
