Alphadle is a passion project, coded by a single developer with AI assistance. This optional subscription exists to cover scaling and do good:
State taxes & Stripe fees (mandatory legal & processing fees).
Server & database hosting to keep Alphadle fast and ad-free.
100% of any remaining surplus is donated to environmental associations and sustainable energy projects.
What is Alphadle?
Alphadle is a daily random letter game. Each day, you get one roll to generate a random sequence of 6 letters. Your sequence is analyzed for interesting patterns and properties, earning you badges and EP (entropy points).
HOW IT WORKS
1ROLL: press the button to generate your daily letter sequence.
2DISCOVER: see what badges your sequence earns based on its properties.
3COLLECT: build your badge collection over time.
4SHARE: show off your rolls to friends.
SEQUENCE RARITY
Your roll's overall rarity is based on your total EP compared to all possible rolls. It shows how your roll ranks:
COMMONBOTTOM 50%
UNCOMMONTOP 50-25%
RARETOP 25-10%
EPICTOP 10-5%
LEGENDARYTOP 5-1%
MYTHICTOP 1-0.1%
COSMICTOP <0.1%
BADGE RARITY
Each badge has a rarity based on how likely you are to roll it. Rarer badges are worth more EP. Badge rarity is determined by probability:
COMMON>10% OF ROLLS
UNCOMMON1-10% OF ROLLS
RARE0.1-1% OF ROLLS
EPIC0.01-0.1% OF ROLLS
LEGENDARY0.001-0.01% OF ROLLS
MYTHIC0.0001-0.001% OF ROLLS
COSMIC<0.0001% (1 IN 1M+)
BADGES
There are many unique badges to collect. Badges recognize patterns like palindromes, alphabetical sequences, repeating letters, syllables, consonants and vowels structures, and more. Some badges are common, while others are extremely rare.
