Herzog is a cross between dominoes and rummy played with six-sided cards. Card play follows the rules of rummy and additional points are scored by creating loops and other forms. Herzog includes a full help menu and also a tutorial. You can save games in play, player profiles and win/loss statistics. You can play against Herzog (computer play) or against another person (pass play). This game is unique. Simple to play, but with some very engaging strategies. Herzog is always 100% ad-free and is a fully off-line app (no Internet connection needed).
Circuit Crawl

The motherboard has fallen, its memory chips are scattered, and one tiny maintenance spark is still online. Guide VOLT-9 through dangerous circuit layers where gravity, timing, and every move matter. Dig through the board, collect the required chips, and reach the exit before falling disks, bombs, patrol scissors, and hunting programs cut your journey short. FEATURES • Tactical digging and gravity-based puzzle action • Hand-built introductory layers followed by endless generated challenges • Falling disks, explosive traps, patrol enemies, and relentless hunters • Simple touch controls designed for portrait play • A level editor for building, testing, exporting, and sharing custom puzzles • Persistent progress, scores, records, and daily rewards • Play in English, Turkish, Spanish, German, Portuguese, or Russian Every layer is a new circuit to read, reshape, and survive. Think before you dig—the motherboard is watching.

Verdict
The clearest difference is ads: Herzog at none against Circuit Crawl's shown. Herzog also leads on iOS requirement (12.0 vs 15.0). Circuit Crawl's advantage is update cadence (weekly vs every 3 weeks). On price, in-app purchases and device support there is nothing between them.
