ABSTRACT:
The present invention relates to a game tool for jumping building block-based stepping stones, comprising a plurality of stepping stone units that can be independently placed flat on the ground for children to step on and jump. As each stepping stone unit is triangularly tilted, a top surface of each stepping stone unit forms a different inclination by changing the combination at a different angle, thereby enhancing the difficulty level of the game. Therefore, it is possible to superimpose and pile up the stepping stone units at a different inclination. Moreover, an anti-slip piece having a different pattern is disposed on a top surface of each of the stepping stone units, thereby preventing slippage and achieving educational and recreational purposes.
