## __Description__

## __Solution__
In the game, you roll a random dice several times and try to reach the target as close as possible.
The target is determined by:
```#define LIMIT 1000 ...uint32_t a_very_random_number(){			// Fair and unpredictable!	float sum = 0 ;       	if (read(fd, rand_vals, sizeof(uint8_t) * LIMIT) & 0x80000000)		return 0 ;	for (uint32_t i = 0 ; i < LIMIT ; i++, sum += (float)rand_vals[i] / (uint8_t)(~0)) ;	return (uint32_t)sum ;  }```
where fd is /dev/urandom, so the number is about 500*LEVEL because it's pretty random.
So the strategy is to choose smallest dice and flip it with 500\*LEVEL/(sides\*0.5+0.5).
For example, in LEVEL 10, you pick 6-sided dice, you should flip it 500\*10/2.5 = 1429 times.

After final battle, you are asked to choose to press GREEN or PURPLE button, press PURPLE and get the flag.
