Number Puzzle App Icon Concepts

Goal: Create a polished presentation board of [app theme] app icon concepts, showing multiple alternative icon directions for a modern mobile app.

Canvas: Wide 16:9 landscape canvas on a warm off-white background, minimal gallery-style spacing, soft shadows, premium design-review mockup aesthetic.

Header: Centered at the top, large elegant serif title text: [headline text]. Under it, a small uppercase tagline with spaced letters: [tagline text]. Use tiny colored dots between the words.

Layout: Arrange exactly 10 rounded-square app icons in a clean 2-row by 5-column grid. Each icon is the same size with consistent corner radius and subtle drop shadow. Add a single centered letter label beneath each icon, exactly A through J.

Icon concepts, exactly 10:
A: Cream monochrome icon with stacked 3D numerals 1, 2, and 3 standing on a circular pedestal, sculptural clay/plaster look.
B: Dark navy icon with four raised rounded number tiles, colored blue 7, cream 3, orange 5, and teal 8, arranged like playful puzzle blocks.
C: Deep purple-black icon with a large gradient numeral 9 in orange-to-magenta-to-violet, with colorful particle dots bursting from the right edge.
D: Dark teal icon showing an orbital logic pattern: concentric circular paths, small white spheres, and a glowing cyan center.
E: Warm ivory icon with flowing rainbow wave bands rising from left to right, small Fibonacci-like numbers above the wave: 1, 2, 3, 5, 8, 13, 21.
F: Dark indigo icon with a geometric network made of thin white connecting lines and dots, with a glowing golden center point like a constellation.
G: Dark teal icon with a luminous infinity loop made from many fine parallel lines, transitioning from cyan on the left to golden orange on the right.
H: Light cream icon with a 3x3 grid of tactile number tiles, numbers 2 4 7 on the top row, 1 5 6 in the middle, 8 3 9 on the bottom; the 5 tile is blue and the 7 and 8 tiles are dark.
I: Dark navy icon with a large glossy white 3D question mark, small colored buttons/dots on it, suggesting curiosity and puzzles.
J: Near-black icon with a circular color wheel or dial around a dark central disk, segmented rainbow colors, plus a small white sphere at the upper right edge.

Visual style: High-end app store icon exploration sheet, soft 3D rendering mixed with clean vector precision, rounded corners, realistic highlights, subtle ambient occlusion, crisp typography, balanced white space, no watermark.

Constraints: Keep the board uncluttered, preserve exactly 10 concepts and the A–J labels, avoid adding extra icons or explanatory text beyond the title, tagline, numbers inside icons, and labels.
