Turkish is agglutinative: göz (eye), gözlük (glasses), gözlükçü (optician), gözlükçülük (the optician's trade). Köken turns that chain into a game. Everyone gets the same three roots each day. Add letters to reach a new word and a branch grows out of the root on screen. Continue from the tip, or branch anywhere you like — gözlük leads to both gözlükçü and gözlüklü. What you have at the end of the day isn't a scoreboard, it's that day's tree. The rule is prefix-chaining, not morphology: a word is a valid extension if it's in the dictionary and starts with the previous one. So "kar" to "kart" counts too. This isn't a grammar lesson, it's the pleasure of finding out. Depth scores, not length. The fourth link in a chain is worth four times. Four short words are worth less than one four-link chain. Find every word on a root and the tree turns gold. No timer. No energy. No lives. As you type, the branch tip trembles to tell you whether a word exists in that direction. At the end of the day it tells you "you found 23 of 41" — it doesn't hide what you missed. Every completed day is planted in your garden. The garden scrolls, its season follows the real one, and morning light differs from evening light. Each word you find shows a one-line meaning. The dictionary works offline.

Verdict

The call

The clearest difference is ads: Block Forge at none against Köken's shown. Block Forge also leads on iOS requirement (13.0 vs 17.0). Köken's advantage is update cadence (every 4 days vs every 2 weeks). On price, in-app purchases and device support there is nothing between them.
