The Big Duel The Bid Duel is a fun addictive game where you can test your math skills. You can choose between 3 game modes and play 1vs1 or 1vsTime Game Modes: - Math - Bigger/Smaller - Shapes Choose between math calculations like: * Addition * Subtraction * Multiplication * Division Choose hardness and play 1vs1 on 1 device or against the time. Let your kids train their math skills with lot of fun and nice animations (Blueprint). Have fun How To Play? Game Mode - Math You will get a math calculation and 3 different results, press the right result to move the rocket to earth. Game Mode - Big/Small You will get a math calculation and a random number in the middle button (that is NOT the right result). Now you must find out if the right result of the calculations is BIGGER or SMALLER than the number in the middle button. Game Mode - Shapes You will see a random shape and you will get 3 different results. Only one result is the right side amount of the shape. Press it to move the rocket to earth. (Circle has 0 sides, Triangle has 3 side)

Irrigation Engineering Practice is an educational application designed to help students understand and practice the principles of irrigation systems, water resources development, and agricultural water management. The app emphasizes structured learning through chapter-wise quizzes, mock tests, and daily quizzes aligned with standard irrigation engineering curricula. Users can practice questions from individual topics, attempt mock tests for comprehensive assessment, and monitor their performance using statistics. The app supports self-study, classroom learning, and examination preparation for civil engineering students. Topics Included 1. Introduction to Irrigation Irrigation engineering concepts, need and advantages of irrigation, types of irrigation, sources of irrigation water, and water resources development. 2. Soil Water Plant Relationship Soil water concepts, field capacity, wilting point, available water, root zone depth, and consumptive use. 3. Irrigation Water Requirement Crop water requirement, duty of water, delta, base period, irrigation efficiency, and water losses. 4. Canal Irrigation Types of canals, canal alignment, canal cross-section, canal lining, and maintenance. 5. Canal Design and Regulation Kennedy’s and Lacey’s theories, discharge measurement, canal falls, cross regulators, and escapes. 6. Diversion Headworks Weirs, barrages, divide walls, fish ladders, and under sluices. 7. Storage Structures Types of dams, spillways, reservoir capacity, forces on dams, and dam safety. 8. Water Logging and Drainage Causes and effects of water logging, surface and subsurface drainage systems. 9. Irrigation Methods Surface, furrow, basin, sprinkler, drip, and micro irrigation methods. 10.
