GAME INTRO ---------------- Smiley Chain is a classic game that has falling group of 2 smilies from top of the screen. The pieces can be moved, dropped, and rotated as they fall. The piece falls until it reaches another smiley or the bottom of the screen. When four or more smilies of the same color line up adjacent to each other, the smiley will connect to each other, blinking and disappear. Smilies of the same color can connect horizontally or vertically, but not diagonally. A chain is made when falling smilies cause a new group of smilies to disappear, making a chain reaction. When player made a chain, you will earn a special bonus: Big Eater or Random Brush that will clear a lot of smilies in a extraordinary way. You can compete your score with other playes via leaderboard worldwide. Now go for it and have fun! CREDIT ------------------ + Sounds generated from Bfxr.

Verdict
The clearest difference is in-app purchases: Smiley Chain at none against Pac.io's 10. Smiley Chain also leads on ads (none vs shown) and review sentiment (75% vs 54%). Pac.io's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (297 vs 4). On price, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Pac.io sells 10 one-off in-app purchases. Smiley Chain asks for nothing beyond the download.
Pac.io holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Pac.io has 297 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 54% of Pac.io's written reviews are positive against 75% of Smiley Chain's, so the app with the better star average is not the one people write more warmly about.
Pac.io ships an update fortnightly, Smiley Chain every 4 months. The most recent releases landed on September 21, 2026 and June 4, 2026 respectively.
