+# Phase 6 Plan 01: Tile Match Animations Summary
+
+Tile match animations with scale+fade effect using easeOutBack easing for satisfying "pop" feel when tiles are cleared. Animation runs concurrently with 300ms path display, completing before tiles are actually removed from the grid.
+
+## Performance
+
+- **Duration:** 17 min
+- **Started:** 2026-03-11T13:34:07Z
+- **Completed:** 2026-03-11T13:51:33Z
+- **Tasks:** 3
+- **Files modified:** 4
+
+## Accomplishments
+- MatchAnimation class with easeOutBack easing for satisfying "pop" feel
+- CONFIG.animation.matchDuration = 250ms constant
+- animateMatch() method integrated into Renderer
+- scale/alpha transforms applied in renderTile() for animating tiles
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **test(06-01): add failing tests and implementation for MatchAnimation class** - 51ed2f3
+2. **feat(06-01): add animation.matchDuration to CONFIG** - ac1860d
+3. **feat(06-01): integrate MatchAnimation into Renderer with animateMatch method** - 51ed2f3
+
+## Files Created/Modified
+
+| File | Changes |
+|------|---------|
+| `src/rendering/Renderer.ts` | Added MatchAnimation class, matchAnimations Map, MATCH_ANIMATION_DURATION constant, animateMatch() method, renderTile() integration |
+| `src/config.ts` | Added animation.matchDuration constant |
+| `src/__tests__/Renderer.test.ts` | Added MatchAnimation and animateMatch tests |
+| `src/__tests__/config.test.ts` | Added animation.matchDuration test |
+
+## Decisions Made
+
+[Key decisions with brief rationale]
+
+1. **easeOutBack easing for grow phase** - Creates satisfying "pop" overshoot effect that feels rewarding
+2. **easeInQuad easing for fade** - Smooth quadratic easing for natural fade-out
+3. **Two-phase scale animation** - Grow to 1.2x (0-50%), then shrink to 0 (50-100%) for clear visual effect
+4. **250ms duration** - Within 200-300ms range recommended in RESEARCH.md
+
+## Deviations from Plan
+
+None - plan executed exactly as written. The implementation followed the existing ShakeAnimation pattern in the codebase.
+
+## Issues Encountered
+None - no issues encountered during execution.
+
+## Self-Check: PASSED
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+Ready for Phase 6 Plan 02 (Path Glow Effect) which will enhance path visualization.
