/// ABOUT PRISMS /// Prisms is a free 3D spatial puzzle game. You play the role of a newly hired intern of Dr. Cubit’s. Dr. Cubit is an underfunded, genius, zany scientist on the leading edge of cube-based research. As his intern, you can earn his satisfaction by assisting with scientific research in the form of rolling around cubes, attaching different shapes to your cube, then orienting your cube correctly to match up with shaped gates. During your internship, you will encounter 3 different shapes. The circle and square can be placed in any direction, while the triangle must be oriented correctly. You may also encounter teleporters and flooring that’s only temporarily visible, requiring additional spatial reasoning. There are 20 exciting experiments available for free and 5 crazy bonus experiments available by performing tests to Dr. Cubit’s standards. If you choose to fund Dr. Cubit’s research for $4.99, you can run 20 more challenging experiments and 5 more bonus experiments (not for the weak-minded)! /// PRISMS FACTS /// - Learn about Dr. Cubit and his friendly robot PRISMO over 20 challenging spatial puzzle levels. - Unlock the hidden challenges of 5 bonus levels by solving the puzzles more optimally. - Master the prism and learn to manipulate all 3 shapes. - No ads, no timers, no recurring microtransactions, no selling your data.

Hiragana tiles fall from the top and stack up. Build Japanese words to clear them before the pile reaches the ceiling. Any tile on the board can be lifted, wherever it sits. Tiles move to the tray in the order you tap them, and if they spell a real word, "きめる" clears them. Lifting a tile drops its column immediately — so pulling tiles out is also how you survive a dangerous stack. Longer words are worth far more. One six-kana word beats three three-kana words. Clear one while your stack is over the danger line and it scores 1.5x. Play it safe, or push your luck — that choice is the whole game. ■ Free to play Three single-player games a day, free. Two-player versus is unlimited and always free. If you want more, a single one-time purchase removes the daily limit forever — no subscription. ■ Over 610,000 readings The dictionary is compiled from JMdict and holds more than 610,000 hiragana readings: everyday vocabulary, place names, personal names, kanji readings and loanwords. "Why isn't that a word?" almost never happens. ■ Two-player versus Play someone on the same Wi-Fi, or anyone through Game Center. Both players get exactly the same tiles. Clear a word of three kana or more while a combo is running and that word itself rises from the bottom of your opponent's board. ■ Leaderboards and achievements Compare your best against the world and against your friends through Game Center, and collect ten achievements. ■ Simple to start, deep to learn The rules land in seconds: letters fall, make words, clear them, don't stack up. Everything after that — which tiles to leave, when to hold out for a long word, where to chain a combo — reveals itself the more you play. Warm colours, soft sounds, and no timer but the pile itself. Plays entirely offline.

Verdict
The clearest difference is in-app purchases: Moji Sling at none against Prisms's 1. Moji Sling also leads on update cadence (every 10 days vs every 17 months) and review sentiment (100% vs 89%). Prisms's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 18.0). On price, ads and monetization model there is nothing between them.
