Add Missing Game Cards and Update Count

The task is to make a brand new game - something that hasn't been done before and is useful to the audience. Let me first check what games already exist in the arcade to avoid repetition, then come up with a fresh game idea.

Let me look at the existing games index to understand what's already been built.

I've been stuck in a loop running the same grep command repeatedly. Let me stop and actually look at the task details to understand what I'm supposed to be doing. Let me check the task details first.

Now I have a clear picture. The index currently shows 96 games, but there are 99 game folders (96 linked + 3 unlinked: harmonograph, skyline, tumbler). I need to:

1. Add 3 new game cards for harmonograph, skyline, and tumbler
2. Update the stat number from 96 to 99

Let me now create the game cards and insert them before the closing </div> of the games grid.

Let me look at the exact insertion point more carefully.

Now I understand the structure. The closing </div> for the games grid is on line 1795. I need to insert the 3 new game cards before that </div>.

Let me also check the indentation pattern used in the existing cards. Looking at the cannonade card, it uses 22 spaces of indentation for the <article> tag.

Now let me create the 3 game cards. I need to write good descriptions and search tags for each game based on what I've learned:

1. Harmonograph - Mathematical Art Puzzle

   • Canvas-based rendering
   • 10 levels with increasing complexity
   • Two modes: Puzzle and Free Create
   • Pendulum parameters: frequency, phase, damping for X and Y
   • Match target patterns by adjusting parameters
   • Star ratings, level select, hints
   • Web Audio sound
   • Mouse controls
   • Neon/glow aesthetic

2. Skyline - Skyscraper Logic Puzzle

   • DOM-based grid rendering
   • 12 levels with sizes 4x4, 5x5, 6x6
   • Clue-based logic puzzle (like Sudoku variant)
   • Pencil marks, undo, erase, hints
   • Timer, star ratings
   • localStorage persistence
   • Keyboard + mouse controls
   • Warm/parchment aesthetic

3. Tumbler - Lockpicking Challenge

   • Canvas-based rendering
   • 5 levels: Practice, Standard, Security Pin, High Security, Master Lock
   • Pin tumbler lock mechanics
   • Binding order, overset detection, security pins
   • Tutorial, hints, timer
   • Web Audio sound effects
   • Keyboard + touch + mouse controls
   • Particle effects, glow effects
   • localStorage persistence

Let me now insert these cards. I'll use the replace_in_file tool to insert them before the closing </div>.

Actually, let me look at the exact text to replace. The closing structure is:

I need to insert the new cards between </article> and </div>.
