and related Eastern spiritualism is not much emphasized in modern incarnations of the game, the central mechanism of snakes and ladders makes it an effective tool for teaching young children about various subjects. In two separate Indonesian schools, the implementation of the game as media in English lessons of fifth graders not only improved the students' vocabulary but also stimulated their interest and excitement about the learning process. Researchers from Carnegie Mellon University found that pre-schoolers from low income backgrounds who played an hour of numerical board games like snakes and ladders matched the performance of their middle-class counterparts by showing improvements in counting and recognizing number shapes. An eco-inspired version of the game was also used to teach students and teachers about climate change and environmental sustainability. Meyer et al. (2020) explored on the basis of Chutes and Ladders with a free and adaptive game project. This refers on the one hand to systemic game pedagogy. The players and the educators develop the game from ground up and set the rules. The second element of the Monza project is mathematization. Over several years, teachers and learners abstract the game experiences into the language of mathematics. Mathematics of the game Any version of snakes and ladders can be represented exactly as an absorbing Markov chain, since from any square the odds of moving to any other square are fixed and independent of any previous game history. The Milton Bradley version of Chutes and Ladders has 100 squares, with 19 chutes and ladders. A player will need an average of 39.2 spins to move from the starting point, which is off the board, to square 100. A two-player game is expected to end in 47.76 moves with a 50.9% chance of winning for the first player. These calculations are based on a variant where throwing a six does not lead to an additional roll; and where the player must roll the exact number to reach square 100 and if they overshoot it their counter does not move. In popular culture The phrase "back to square one" originated in the game of snakes and ladders, or at least was influenced by it – the earliest attestation of the phrase refers to the game: "Withal he has the problem of maintaining the interest of the reader who is always being sent back to square one in a sort of intellectual game of snakes
