Experience Points (XP) are the currency of BudiBadu. You earn XP based on the inherent complexity of the problem and the number of languages you use to solve it:

• Easy Problems: 10 XP per accepted answer.
• Medium Problems: 25 XP per accepted answer.
• Hard Problems: 50 XP per accepted answer.

Pro Tip: Solving a single Medium problem in 4 different languages nets you 100 XP—the same as 10 Easy problems in 1 language!

Most systems cap you. BudiBadu does not. We use a dual-phase leveling system:

• Tiered Phase (Levels 1-15): Rapid growth with curated title changes and evolving badges. Each tier requires a specifically mapped amount of XP.
• Omniscient Phase (Levels 16+): For the elite. The XP gap between levels increases by exactly 500 XP per level, creating a linear but increasingly challenging path to infinity.

Consistency is the differentiator between good and great. BudiBadu tracks your daily engagement intensity:

• Current Streak: Number of consecutive days you have solved at least one problem.
• Longest Streak: Your all-time record for mental endurance.

High streaks are displayed prominently on your profile and provide periodic "hidden" multipliers to your global ranking influence.

As you climb, your public badge evolves. From your initial status as a Beginner, you will eventually reach prestigious titles like Omniscient and beyond. These badges are not just cosmetic; they represent verified hours of logical heavy-lifting and problem-solving expertise.
