Build a 2D arcade game called “Simorgh Flight”. The Simorgh flies forward while the scene scrolls; the player flaps with Space or a click to rise, and gravity pulls it down. Obstacles (mountains and storm clouds) come at random intervals and must be threaded through. Golden feathers give bonus points. The player has 3 lives. The score grows the longer you survive, and the game slowly speeds up. It needs a start screen, a score and lives display, pause with P, and a game-over screen with restart on Enter. All sounds are made with the Web Audio API, without audio files: flapping, picking up a feather, a crash, and a short looping background tune. All graphics are drawn on a Canvas.

یک بازی آرکید دوبعدی به اسم «پرواز سیمرغ» بساز. سیمرغ رو به جلو پرواز می‌کنه و صحنه حرکت می‌کنه؛ بازیکن با Space یا کلیک بال می‌زنه و بالا میره و با جاذبه پایین میاد. موانع (کوه‌ها و ابرهای طوفانی) با فاصله‌های تصادفی میان و باید از لابه‌لاشون رد بشه. پرهای طلایی امتیاز اضافه دارن. بازیکن ۳ جان داره. امتیاز با زنده موندن زیاد میشه و سرعت بازی کم‌کم بیشتر میشه. صفحه شروع، نمایش امتیاز و جان، توقف با P، و صفحه پایان با شروع دوباره با Enter داشته باشه. همه صداها با Web Audio API و بدون فایل صوتی ساخته بشن: بال زدن، جمع کردن پر، برخورد، و یه موسیقی پس‌زمینه کوتاه و تکرارشونده. همه گرافیک با Canvas کشیده بشه.

Build an ant colony simulator on a Canvas. The nest is in the middle and three food sources sit near the corners. 2,000 ants leave the nest and wander. When they find food they carry it home. They lay two kinds of pheromone, one leading to food and one leading home, which the other ants follow and which slowly evaporate. Pheromones show as faint coloured trails. Dragging the mouse draws walls the ants cannot cross, a right-click drops new food, and sliders change the evaporation rate and the simulation speed. A stats panel shows the number of ants, the food collected and the FPS. It must run smoothly with 2,000 ants.

• ✓Shadows are visible. · juryClear dark cast shadows from the structure and fountains are visible across the paths and lawn in screenshots 1, 2, and 4.
• ✗Architectural detail such as patterns or windows appears on the tower body. · juryThe tower body consists solely of plain TubeGeometry meshes without any patterns, stone tiling texture, or windows.

Build a 3D scene of Tehran's Azadi Tower with Three.js. The tower must be recognisable: a wide base with the large central arch, a body that narrows upward in a curve, and the chamber at the top. It stands in the middle of a square with grass, a fountain and footpaths. Dragging the mouse orbits the camera around the tower and scrolling zooms. A “time of day” slider from 6 am to midnight changes the sun's direction, the sky colour and the shadows, and after sunset the tower's lights come on. Shadows are on. Load no external models or images; all geometry is built in code.

با Three.js یک صحنه سه‌بعدی از برج آزادی تهران بساز. شکل برج باید شناخته بشه: پایه پهن با طاق بزرگ مرکزی، بدنه‌ای که با انحنا رو به بالا باریک میشه، و اتاقک بالای برج. برج وسط میدانی با چمن، فواره و مسیرهای پیاده باشه. دوربین با درگ موس دور برج بچرخه و با اسکرول زوم کنه. یه اسلایدر «ساعت روز» از ۶ صبح تا ۱۲ شب جهت نور خورشید، رنگ آسمان و سایه‌ها رو عوض کنه و بعد از غروب چراغ‌های برج روشن بشن. سایه‌ها فعال باشن. هیچ مدل یا تصویر خارجی لود نکن؛ همه هندسه با کد ساخته بشه.

Build a beautiful virtual Iranian santur. A trapezoidal walnut santur with bridges, tuning pins and traditional ornament, with at least 18 notes over two octaves drawn on screen, plus a pair of santur mallets. The player plays by clicking the strings or with the keyboard, and the key map is shown on screen. Sound is made with Web Audio and should sound like a santur: a struck string instrument with paired strings (for example with Karplus-Strong), natural decay and resonance, and several notes at once. A dastgah selector, at least Shur, Mahur and Segah, changes the tuning, with the koron and sori (quarter-tone) notes tuned correctly. A struck string visibly vibrates. It has a “play a sample” button: pressing it lifts the mallets and they play a short piece of 20 to 40 seconds in the chosen dastgah, each mallet landing exactly on the string whose note sounds at that moment. The piece should feel like traditional Persian music: a calm opening, a riz (the fast repeated strokes that are the santur's signature) and a cadence to the tonic. Compose the melody yourself; do not use any known song or published piece.

Build a complete Persian, right-to-left landing page for a fictional book café in Shiraz called “Autumn Book Café” that tells a story as you scroll: “a day at the café, from morning to night”. As the page goes down, the light and the sky move from morning to sunset to night, steam rises from a cup, autumn leaves fall and image layers move at different speeds (parallax). It has real 3D effects, such as a book that opens in 3D space as you scroll or menu cards that tilt with the mouse (CSS 3D or Three.js). Sections: a header with a menu, a hero with a tagline and a booking button, a drinks and cakes menu with prices in toman, an about section, the week's events (such as a poetry night and a reading), a table booking form, and a footer with the address and opening hours. The Vazirmatn font from Google Fonts, and every number in Persian digits. No external images; illustrations are made with CSS, SVG or Canvas. The booking form takes a name, a mobile number (starting with 09, 11 digits), a date and the number of guests, shows errors in Persian next to each field and a success message after a valid booking. Mobile numbers typed in Persian digits are accepted too. Animations are smooth, and heavy motion turns off for users who enabled “reduce motion”. The page works on mobile (390 px wide) and desktop. Write the copy yourself, natural and not like a translation.

Build an interactive Solar Hijri (Jalali) calendar. A month view where the week starts on Saturday and Fridays are coloured as holidays. Each day shows its Gregorian date in small type. Previous and next buttons move between months and years, and a “today” button jumps back. Today is highlighted. Mark the fixed official holidays: 1 to 4 Farvardin, 12 and 13 Farvardin, 14 and 15 Khordad, 22 Bahman and 29 Esfand. Clicking a day adds a note, and notes stay after the page is closed. A converter takes a Jalali date and gives the Gregorian one, and back. Use no external library. Month names and numbers are in Persian.

Build a generator of Persian girih and tile patterns. The pattern rests on real girih geometry: stars and shamseh rosettes with exact symmetry, repeated on a grid, with tiles that meet without gaps. Sliders change the symmetry (6, 8, 10 and 12 points) and the line thickness, and the user picks from colour palettes inspired by the tiles of Isfahan (turquoise, lapis, gold, white). When the pattern changes, the lines draw themselves with an animation. A “save image” button exports a PNG.

Build an online shop for Iranian handicrafts called “Bazaarcheh”, in Persian and right-to-left, with two tabs: “Shop” and “Admin panel”. The shop shows 6 products (such as a kilim, minakari enamel, khatam inlay, ghalamkar print, pottery and termeh) with prices in toman and stock. The user adds products to the cart or takes them out, sees the total, and places an order with a form for name, mobile number and address. Ordering more than the stock is not allowed. A placed order appears in the admin panel as “pending”. The admin can change its status to “shipping”, “delivered” or “cancelled”. Placing an order lowers the stock and cancelling restores it. The admin can edit a product's price and the shop shows the new price at once. A simple sales figure (the total of delivered orders) is shown. All data stays after the page is closed.
