Building Four Wager-Based Mini Games

Mini-games add another layer of engagement by giving players short, repeatable gameplay experiences outside of the main case-opening loop. For Case Paradise, I built a collection of four wager-based mini-games designed around quick sessions, competitive interactions, and replayability.

Each mini-game used the same core principles: server-controlled outcomes, secure wager handling, consistent payout logic, and animations that made every result feel rewarding.

The system supported both player-versus-player and player-versus-bot experiences, allowing players to participate even when another opponent was unavailable.

Because every mini-game involved in-game currency, the most important part was creating a reliable wager system. Every game had a maximum wager limit of 1,000,000 currency to protect the economy and prevent excessive risk.

The server controlled wager validation, game state, and payouts. Players could request actions through the client, but the final result and currency changes were always decided by trusted server logic.

• -Server-side wager validation
• -1,000,000 currency maximum wager limit
• -Secure payout calculations
• -Replay state management
• -Animation synchronization with results

Coinflip was designed as a simple 50/50 risk game where players could challenge another player or play against a bot.

The first player creating the match was assigned heads, while the second participant — whether a real player or a bot — received tails. The winner was then determined with equal 50:50 probability.

After the result, players could instantly replay. If both players selected replay, the match would restart. When playing against a bot, selecting replay immediately created another round.

The experience included a synchronized coin animation with a 2x payout for the winning player.

Dice Roll was a solo mini-game focused on prediction and risk. Players placed a wager and selected one possible dice face from 1 through 6 before the roll animation began.

The server generated the result while the client displayed the dice animation. A correct prediction rewarded players with a payout approaching 6x their wager.

Because this was a solo experience, replay functionality allowed players to quickly start another attempt without leaving the game flow.

Rock Paper Scissors expanded the competitive system by combining player interaction with timed decisions.

Players could challenge another player or use a bot opponent. Each round gave players a limited decision window, requiring them to select rock, paper, or scissors before the timer expired.

Matches continued for up to 10 rounds. If the game reached the maximum number of rounds without a decisive winner, the system selected a winner automatically.

Similar to Coinflip, players could replay immediately after the match ended.

Higher Or Lower focused on progressive risk. Players started with a wager and were shown a number, then predicted whether the next result would be higher or lower.

Correct predictions allowed players to continue through up to 10 rounds, increasing their potential payout after every successful guess.

Unlike the other mini-games, players had control over when to stop. They could cash out before taking another risk, with a maximum possible payout of 2x.

Although each mini-game had different rules, they all shared the same foundation: reliable state management, secure currency handling, and clear feedback through animations.

Creating a reusable structure meant new mini-games could be added without rebuilding the entire wager system from scratch.

The biggest challenge with wager-based gameplay is balancing excitement with reliability. Players need fast results, but every transaction must remain accurate and protected.

Building these mini-games reinforced the importance of separating presentation from game logic. Animations create the experience, but server-authoritative systems create the trust behind it.
