Question 1

Do I need an account to play Dokicode?

Accepted Answer

Yes. You sign in with Google so your heroine, story progress and solved problems are saved to your account. Solving problems also needs the Dokicode Chrome Extension on desktop Chrome or Edge, which brings your LeetCode results back to the study room.

Question 2

What algorithm study plans are included in Dokicode?

Accepted Answer

Dokicode includes 12 structured algorithm study plans covering over 2,000 LeetCode problems across Track 1 (Sliding Window, Binary Search, Monotonic Stack, Data Structures, Bit Manipulation, Greedy, Math, Strings) and Track 2 (Linked Lists & Trees, Grid DFS/BFS, Dynamic Programming, Graph Algorithms), plus 5 curated interview lists: Blind 75, Grind 75, Grind 169, NeetCode 150, and NeetCode 250.

Question 3

Should I choose Blind 75, Grind 75, NeetCode 150, or the 12-plan algorithm route?

Accepted Answer

If your coding interview is in 2 to 6 weeks, start with Grind 75 (5 weekly schedules, 100% free LeetCode problems) or Blind 75 (75 foundational problems across 18 topics). If you have 6 to 12 weeks, choose NeetCode 150 or Grind 169 for deeper pattern repetition, or NeetCode 250 for gentler warm-ups per topic. For systematic mastery with zerotrac contest ratings, follow the 12-plan algorithm route from Sliding Window to Graph Algorithms. Progress is shared per problem across every plan in Dokicode.

Question 4

Is Dokicode free to use, and how do its hints avoid spoiling LeetCode solutions?

Accepted Answer

Yes, Dokicode and its Chrome Extension are free to use. Instead of showing full editorial code that spoils the problem, your heroine offers a 4-step progressive hint ladder: Step 1 (Direction), Step 2 (Key Idea), Step 3 (Approach Outline & Target Complexity), and Step 4 (Edge Cases & live coaching).
