Key takeaways
- MTG Arena: deeper rule set, draft modes for groups up to 8 in a private lobby, but keeping a competitive collection typically means grinding daily quests or spending roughly $50–$100 per set cycle.
- Hearthstone: faster matches (typically 8–12 minutes vs. 15–25 for Arena), friendlier to casual players, but fewer multiplayer-format options beyond 1v1 and Battlegrounds (8-player auto-battler, which is a solid pick for groups since private lobbies support 8 friends).
The best card game to play online depends mainly on your group size and whether everyone is willing to install something: for groups of 4+ who want a free, instant option, UNO! Mobile or the browser version of Exploding Kittens works best; for smaller groups (2–4) who want depth, Magic: The Gathering Arena or Hearthstone are the strongest choices; and for larger party groups, Tabletop Simulator or tabletop websites like PlayingCards.io cover nearly everything.

Quick Pick by Group Size
Player count is the single biggest filter. Most digital card games are built for 2 players, so a group of 6 narrows the field fast.
| Group size | Best picks | Cost | Cross-play |
|---|---|---|---|
| 2 players | MTG Arena, Hearthstone, Gwent | Free-to-play | Mobile + PC |
| 3–4 players | UNO! Mobile, Skyjo (via apps), Balatro (solo, not recommended for groups) | Free or cheap | Varies |
| 4–8 players | Exploding Kittens, Card Party, Codenames online | Free–$10 | Partial |
| 8+ or custom games | PlayingCards.io, Tabletop Simulator | Free / ~$20 one-time | Browser works everywhere |
Head-to-Head: The Main Contenders
MTG Arena vs. Hearthstone (2 players, competitive)
Both are free-to-play 1v1 card battlers on PC and mobile with cross-play between platforms. The real difference is matchmaking depth and cost of staying competitive:
- MTG Arena: deeper rule set, draft modes for groups up to 8 in a private lobby, but keeping a competitive collection typically means grinding daily quests or spending roughly $50–$100 per set cycle.
- Hearthstone: faster matches (typically 8–12 minutes vs. 15–25 for Arena), friendlier to casual players, but fewer multiplayer-format options beyond 1v1 and Battlegrounds (8-player auto-battler, which is a solid pick for groups since private lobbies support 8 friends).
Verdict: pick Hearthstone if your group mixes casual and competitive players; pick MTG Arena if everyone enjoys longer, more strategic games or you want to draft together.
UNO! Mobile vs. Exploding Kittens (party groups)
- UNO! Mobile supports 2–4 players online (some modes up to 8 in team formats), is free-to-play with ads, and has essentially zero learning curve. Private room codes take about 30 seconds to set up.
- Exploding Kittens (paid app, usually under $5, plus a browser version) supports 2–5 players, games run 10–15 minutes, and it works across iOS and Android but not PC natively.
Verdict: UNO wins on price and accessibility; Exploding Kittens wins on chaos and fun for mixed-age groups.
PlayingCards.io vs. Tabletop Simulator (custom or classic games)
If your group wants to play classics — Poker, Rummy, Crazy Eights, Hearts — without a dedicated app:
- PlayingCards.io: free, entirely browser-based, up to 12 players per room, no accounts needed. You share a room link and drag cards on a shared virtual table. There are no enforced rules, so the host needs to know the game — that’s the trade-off for supporting literally any card game.
- Tabletop Simulator: a one-time purchase (usually $15–$20) on PC with thousands of community-made card game workshops. Supports up to 10 players. Every player needs a copy, though, which makes it expensive for large groups.
Verdict: PlayingCards.io is the clear winner for cost and friction — nobody installs anything and mobile users join the same room as PC players.
What Actually Matters: Matchmaking, Cross-Play, and Real Cost
Cross-play and platform availability
| Game | PC | iOS/Android | Browser | Cross-play | Max players |
|---|---|---|---|---|---|
| MTG Arena | Yes | Yes | No | Yes (full) | 2 (8 in private draft) |
| Hearthstone | Yes | Yes | No | Yes (full) | 8 (Battlegrounds) |
| UNO! Mobile | No | Yes | No | iOS↔Android only | 4–8 |
| Exploding Kittens | No | Yes | Yes | iOS↔Android | 5 |
| PlayingCards.io | Browser-based (all devices) | Yes | Universal | 12 | |
| Tabletop Simulator | Yes | No | No | PC only | 10 |
Free-to-play math: what “free” really costs
A spec sheet says “free-to-play,” but the useful number is time-to-competitive. Here’s a rough calculation for a free MTG Arena player:
- Daily quests + weekly wins ≈ 10,000–14,000 gold per week, roughly 10–14 packs’ worth of value.
- A competitive Standard deck needs ~40–60 rare wildcards; earning that purely free takes roughly 8–12 weeks of consistent daily play.
- Alternative: a one-time ~$50–$100 spend per set, or drafting (limited play) which converts gold into cards far more efficiently than buying packs.
By contrast, PlayingCards.io, UNO!, and Exploding Kittens give you the complete game for $0–$5 with no progression gate — which is why they beat the “bigger” card games for casual friend groups.
Matchmaking vs. private rooms
For playing with friends specifically, private lobbies matter more than ranked matchmaking. Check before committing:
- Games like UNO! and Exploding Kittens use room codes — no friend-list systems, which actually makes joining easier for mixed platforms.
- MTG Arena’s direct challenge mode is 1v1 only; group play requires scheduling a private draft.
- Hearthstone Battlegrounds private lobbies fill empty slots with bots — handy when you’re 5 people in an 8-player format.
The Decision Matrix
| Your situation | Pick this | Why |
|---|---|---|
| Mixed phones and PCs, zero setup | PlayingCards.io | Browser link, any card game, 12 players |
| 2–4 casual players, phones only | UNO! Mobile | Free, instant room codes, no learning curve |
| Two competitive players | MTG Arena or Hearthstone | Real matchmaking, cross-play, ranked ladders |
| Group of 5–8 wanting chaos | Exploding Kittens | Short games, easy rules, cheap |
| Want any game ever made, all PC users | Tabletop Simulator | Workshop library, physics sandbox |

Can we play card games together on different devices?
